I’ve been having this problem when i save my blender projects it will not save my animations. I am running blender 2.65 on mac osx 10.8.2.
Has anyone else had this problem?
Is the animations you were missing currently on an armature or object? If not press the F next to the action name.
Like cam.dudes has pointed out, you must press the F button next to the action selector for it to be assigned a fake user and saved with the blend file. Not sure why, since you can manually delete resources with shift + X button click now since the 2.5 days, but that’s a discussion (that I’m pretty sure has already been had) for the general Blender forums.
