R15 Character Animation Arm Folds In

After the recent update to replace Motor6Ds in avatars, this has caused issues for my game where the arm is supposed to detach.

When the upper and lower part of either arm of a character is parented outside the character or deleted it causes the remaining arm to permanently fold into the character. All the other animations of the player seem to still work correctly. This happens with both rigs using Motor6Ds and AnimationConstraints.

This is an old picture of a player with their arm missing in my game, this is how it is supposed to look:

How it looks currently when an arm is removed from a player or other characters using R15:


This happens on any game, it can be done on a new baseplate easily by:

  1. Pressing play
  2. Going to server view
  3. Selecting the players character
  4. Deleting or changing the parent of both an upper and lower arm on the same side
