MMF2 deleting Active Object Animations

[WhatPixelYouOn]

Just spent a while drawing some animations in the Active Object editors only to have the object I was working on revert back to an older version of it after I clicked ok. Undoing would put the new animations back in to the last point I came out and saved it, but then redoing would just remove all the work I put into it, reverting all the animation frames back to very old ones I was using. I've noticed this happen with MMF2 quite a bit recently and it's incredibly annoying. Can this be fixed please?

Can you try it in Fusion 2.5 and see if the behavior is the same?
