I am using the humanoid method ApplyDescriptionReset() in combination with the new ‘Avatar Settings’ feature in studio. Specifically, it is configured to use ‘Consistent Gameplay’ with the ‘Single Collider’ option - and hence the character has a CollisionPart instance.
This combination breaks my character such that it can no longer move, and has this falling animation as if there is something wrong with the collisions:
I am simply applying my own avatar humanoid description using ApplyDescriptionReset() and fetching the humanoid description using Players:GetHumanoidDescriptionFromUserId().
This problem only happens with Humanoid:ApplyDescriptionReset and not Humanoid:ApplyDescription.
