So I found that bug is reproducing with old mannequin animations, maybe ones created before epic’s dipping fix
It’s not reproducing with default anims or aimstarterpack ones in new project (but my project exists more than half a year), but is actual with some marketplace anims (Pushable Actor in Blueprints - UE Marketplace)
I think they were not updated to fixed mannequin, and in may concern other marketplace anim packs
I left an invitation to asset’s dev to join our conversation
