Issue description

In my game, I have a BoneAttachment3D node which controls where the arms of the character are positioned. Before reparenting, the arms are influenced by outside animations. When I equip a weapon I would like the arms to follow the weapon's animations too, so I reparent the BoneAttachment to that weapon, however that stops all influences on the arm bones from happening. Manually moving the BoneAttachment into the weapon in the editor before playing has it work fine, so it seems to be an issue with the reparent() functionality. Additionally, reassigning the BoneAttachments' external skeleton during runtime in the Remote tab does not fix it.

What it looks like:

Steps to reproduce

Create a BoneAttachmen3D node.
Enable External Skeleton and Override Pose.
In a script, call boneAttachment.reparent(parent)
In game, the BoneAttachment will stop having any effects

Your debugger also shoots up with something every frame after the reparent() method is called. can you provide more details on what that error is?

Ah thanks, I'm fairly sure that was an unrelated error with my player code.

Not sure why they appeared as soon as i equipped the weapon in the video, that doesnt usually happen. Even when they dont pop up the boneattachment stops working anyway.

Will keep an eye to see if it happens again in the future though.
