There a big bug in 3.8.59 that causes images to be hidden when you undo your animation. I think its turning any slots that are keyed to have no images visable every time you undo a segment that has slotted keys past what you undid.

This occurs no mater what rig I open up so i'm sure it's easily replicated.

Is there a reason why I havn't gotten a reply about this yet. I think it's a bit of a big problem mainly because you can't undo it once it happens. So if you ever hit undo then your practically left with reloading your project or attempting to fix it. It would be great if this were a priority scince it does hinder that animation progress in the editor.

Thanks, glad to hear it. I'm looking forward to the fix so I can get back to animating normaly.

Thanks, I realy appreciate this fix and i'm sure others do as well. Awesome work.
