Sorry for not being here for a while. Been busy doing other project. I was planning to make a step-by-step video of this issue after finishing it, but I guess I missed the timing. :bigeyed:
I'm really glad that it's fixed now!
You guys really are the best dev team in the world. 
I've been trying to reproduce the graph breaking.
I just made a simple loop to test that bug.
This happens in every project.
And the result changed everytime I re-opened a project.
Here's what I found out.
2-1. Graph will lose random beziers.
2-2. Graph will break losing beziers.
The common thing about these two is, they lost one or two beziers and it's ruining the graph.
The bug also seemed to appear in both ways on one project, but it stayed in one form before opening a new project.
In this session the trans graph will always be broken while the scale graph will always go linear.
The way to get the different results was just re-opening a project. Not even had to close Spine. And by re-opening over and over, sometimes pasting didn't break and worked. That's wired.
And I checked if there's specific pattern or something about what causes which key to break, but it was just random and 'the key that breaks' will always be the same key before opening a new project, too.
Thanks for the answers! But here's the things I still don't get it.
I'll just put the original last sentence of this section here.
Can you explain [can't deselect keys by clicking on graph editor's empty area when "Drag to edit" option is on after 4.1 update] is a bug or an intended change?
Maybe we're talking about different things.
At 4.0, 'Drag to edit' was an option that allows us to move the selected keys by dragging on emtpy area.
And still, it allowed us to deselect keys by clicking on empty area.
This was a super handy option and I believe it was a default on option.
After 4.1, this option doesn't allow us to deselect keys by clicking on empty area anymore. Clicking just acts the same like dragging, it holds the key.
I just don't know why the team has changed the previous version that worked perfectly.
Two reasons why deselecting on empty was good and saved decent amount of time.
a. I can use much easier box selection like controlling units in Starcraft instead of directly clicking on the exact key: which is a very small square point.
Since I can deselect anytime, I can use box selection all the time. And that makes changing selections very quick. Plus, I don't even have to directly click on the keys move them.
(If I can't deselect, I can't use box selection because it won't make box and just drag the selected keys.)
(ctrl drag does make box anytime, but it 'adds' keys to current selection, doesn't reset or change. so, that doesn't help the situation now.)
b. I don't have to re-select anything.
If I use spacebar to deselect keys, I end up also deselecting the bone I was animating. That makes me to select the bone again and again.
Deselecting bone will also bring up all the graphs in the current animation. Do I have to lock the list or filter it out everytime to see the graph I was working on?
Since it's different from the original way Spine worked / I worked few days ago, this way is really uncomfortable, too.
But it's less time-comsuming. That's why I'm just adapting to new control.
Holding CTRL while dragging doesn't let me to move keys horizontally / vertically. ?
Is there a hot key automatically locks x/y axis in Spine?
I mean. even without axis lock, Spine's snap feature is good. But I'm struggling to move horizontally since it's snap, not lock. This really bothered me enough to make me set up a y axis lock hot key. It'll be really nice to know if there's one.
I love to make cycle animations first, loop them and adjust little bit to make base animations look more natural.
To do that, I often copy & paste the keys to extend the animation.
After 4.1 update, when I try to use the same method, the graphs just break.
Seems like the weights are gone to space.
This may seem like a minor visual issue, but they actually ruin the animation.
I can fix them by re-doing all the beziers, but they're too many and slowing me down.
And about the new control, before 4.1 update, in the graph editor, I could deselect keys by clicking empty spaces on the graph editor and move the selected keys when dragging.
But after 4.1, I can't deselect keys by clicking on the editor if "Drag to edit" option is on. It allows me to only move the selected keys. I have to chose only one option between click to deselect or drag to move. (I actually have only one option because new editor doesn't allow me to deselect with the "Drag to edit" option on.)
So, it forces me turn the option off and use different controls I've been using in Spine for years.
I really wish I could use the original way of control.
The last things I want to report is, where is the x y axis lock indicator?
And why value/shape button is hidden in small button in the corner?
Since shift+dragging works different in spine, I often just locked axis to move keys horizontally / vertically.
The hotkeys I set seems to work for now, too. But I can't see if it's locked or not.
I love the new export options and new sequence feature, but 4.1 was a total disaster for me for the past few days.
+Edit
I found out how to easily fix the graph
What I had to do is just touch any keyframe in the editor.
A few weeks ago, I got hoykey issue after using beta version and changing to newest stable version.
Invalid action: New Physics Constraint
Invalid action: Physics Constraint - Edit Physics
Invalid action: Edit Physics - Modify
Invalid action: Edit Physics - Create
Invalid action: Edit Physics - Delete
I managed to get rid of that message by manually deleting them in hotkey file.
But that got me curious and I looked up the physics constraint on forum and found out new constraints are under development and planning to be released on 4.1 beta.
Today I got 4.1 stable build and saw the physics constraint hotkeys in the change log, but they doesn't seem inculded.
I'm not complaining about that, I was just too excited to hear that they are coming to Spine. I am a former 3D animator and I'm really looking forward to create rigs more similar to ones I used to work with or more complex and flexible rigs as After Effect scripts or Toon Boom Harmony's.
So it's like waiting favorite movie's sequel to come out for years to me.
Is there any updates or new plans that Esoteric can share?
btw, this never bothered me, but I was always curious about this. Why is my launcher so blurry?
Hello from Korea! I translated the blog post recently, and I found out that the avatar in the post was actually Demon's Souls' title image while searching about the games you mentioned. You really love the Soulsborne series, haha!
