@AngelCutebXtch what do you mean, like you open your scene and Timeline is empty?
There's one case that I know of, if your animation has too many keyframes, at one point
Virt-A-Mate will crash (because of it's serialization engine), the only solution to this is to reduce keyframes (tomorrow I'll release a new version with much better keyframe reduction), but it should clearly show an error in the VaM error window when it's the case. If you say there's _nothing_ showing up in the errors log when saving, then I don't know either.
My ideas: send the saved JSON file (you can send it privately) and I'll investigate. You could also record the screen showing saving the scene, _maybe_ I'll see something you didn't...
It's always possible that you got a very unique bug, in which case I'd also like to fix it
