Short description of error
After linking and library overriding a complex rig, various actions can cause a crash with this backtrace:
Trying to simplify the rig further has been a nightmare. With 24 attempts over the past hour, all I managed to do while still getting the crashes is delete all but one mesh object - but the backtrace is going on about IK functions, so I don't understand why the mesh would be relevant. Even so, removing other bones also seems to make the crash go away... I am very confused.
Exact steps for others to reproduce the error
- Rig file:
- Link CH-sprite collection in a fresh project
- Make library override
- Animate the "IK-MSTR-P-Wrist.L" bone with a couple of keyframes
- Save and restart blender
- Do actions such as playing animation, changing action, select, deselect all, box select, Save As
- It should crash.
