Crashing in inscribed ultimatums.“Bone has no vertex influences” errors

Hi everyone 😄

I’ve been experiencing repeated crashes during Inscribed Ultimatums today

The crash doesn’t happen every time, but it has occurred 3 times within about 3 hours of gameplay and each time costing me around 24 Divines total.

The game freezes for a second or two and then closes to desktop without showing any error.

Checking my LatestClient.txt, I found a large block of repeating critical errors just before every crash:

[CRIT Client][Art/Models/MONSTERS/VaalMonsters/ProwlingShade/attachments/Necklace/rig.ast]
Bone: phys_skinned_r_brush_1_jntBnd has no vertex influences
(and similar messages for multiple bones, repeated hundreds of times)

It looks like something is wrong with the "ProwlingShade" monster model or its attachments that are used in Ultimatums.

System details:
Client: Standalone (non-Steam)
Renderer: Vulkan
OS: Windows 10
GPU: NVIDIA (driver 581.80)
Game version:Latest

What I’ve tried:
Cleared shader and cache folders
Switched to DirectX 12(Crashed here as well with the same error)
Even after repairs, the crash still happens occasionally in Inscribed Ultimatums

Steps to reproduce:
Enter an Inscribed Ultimatum
Start the encounter,crash may occur shortly after Trialmaster spawns mobs

It doesn't happen every single run, but enough times to make this mechanic very risky to play, has anyone else had the same issues?

The file in question is Art/Models/MONSTERS/VaalMonsters/ProwlingShade/attachments/Necklace/rig.ast

Bug Report ID: #512,861,370



EDIT:

Windows event log shows this:
Faulting module: PathOfExileSteam.exe
Exception code: 0xc0000005

This also happens in normal ultimatums in maps.So ultimatum is pretty much unplayable.I do not know how no one is talking about the game breaking bug?

Yeah, I got the same problem, so i quit doing inscribed ultimatums because it occurs too frequently.

+1

I’m running into this problem too.
The error line keeps repeating over a hundred times, and then the game crashes right in the middle of an ultimatum.
Really hope the devs can patch this soon 🙁

There were some crash fixes in tonight's patch, what about this one?

Unfortunately no,the patch did not fix the ultimatum :S
