UE 5.7 - Offset Root Bone node is adding weird rotation to the character mesh after playing a montage

Hey!

I updated from 5.6 to 5.7 yesterday and I have a weird issue. I didn’t do any change just updated the project. I’m using motion matching (very similar setup to Epic example) and now, after playing a montage, the Offset Root Bone adds a “random” rotation to the mesh. Capsule its fine, its only a root rotation.

Something about the node on 5.7 we should be aware of and update in our projects??

Playing with different settings I have noticed the problem is gone setting up Inertialization as Blending Out method but I would prefer having the flexibility of choosing whatever I want instead of using Inertialization all the time.

I also noticed when I used rewind debugger to understand what is happening and I play a montage, the engine crashes, is this a known bug? or it’s specific to my project?

Thanks
