Maya deletes part of animation

[Laury.vansever]

So I use Maya for an animation.

I tend to have the following problem:

When restarting Maya, I tend to sometimes lose a part of the animation.

This mostly happens in the legs, I use a basic bony.

Any tips to recover my animation(I don't want to have to reanimate it all again)?

Wether some of the animation can be recovered or not depends on what caused the problem in the first place. And there isn't really enough information here to determine that.

Is all the Animation on those controllers lost or just part of it?
What color do the indicators next to the values in the channelbox have on those controllers?

Did you get any Error messages when you reopened the file?

Are you sure you reopened the correct save file? sometimes you accidentally change workplace and the autosave gets saved into a different folder.

Could you attach a zipped .ma of the Scene in question?

Have a nice day!
