Inscribed Ultimatum crash (Prowling Shade log)

I was trying Inscribed Ultimatum, and it crashed right before I finished the objective (I was standing in the final circle). After some research, I found that someone posted on reddit that before this specific crash, their log has the repeated lines, so I went to check my log and I found the same lines.

[Art/Models/MONSTERS/VaalMonsters/ProwlingShade/attachments/Necklace/rig.ast] Bone: phys_skinned_r_brush_1_jntBnd has no vertex influences

This line repeated around 10 times before the crash. The reddit thread that mentioned this was 4 months ago, so I want to let you know it's still not fixed.

Seems like this specific crash will only happen in 'Standing in Circles' objective with Divine Orbs as rewards.
