Sorry for the late reply! This sounds very weird, as animation keys are always loaded from the skeleton .json
or .skel.bytes
file, I wonder where these old keys are coming from. Are you sure that you do not have a second duplicate of the skeleton that is used instead?
If you are sure that this issue is not related to using and updating the wrong assets, could you please create a minimal Unity project that still shows the issue, and send it as a zip package to contact@esotericsoftware.com? Then we can have a look. Please also briefly mention the url of this forum thread in the email so that we know the context.
