Bug made me die to kitava act 10 hc

Client crashed and this message popped while hitting kitava's heart phase 2.

"Metadata/Decals/bloodnew.atlas":Reference count for loaded resource Metadata/Decals/bloodnew.atlas is 1.

Around 16-17 hours later I have this crash again with another report message :|

I have w10 dx11 graphics are all medium, Idk what to do I'm a hc player and this is getting out of hand.. I can't an entire week if suddenly the game will crash at random moments, this time I wasn't in no big fight it was just casual act5.

This is the error message:

"Art/Models/Interface/CharacterSelection/Crow/Rig_c5f44bea.smd":In source code file:
F:\buildslave\build\production\source\windows\visual\device\d3d11\IndexBufferD3D11.cpp at line 41, Processing file:

Error: -2005270523
Message: Unable to create index buffer.

Just for the record, afting crashing one more time I found what seems for now (been playing for 2 days without crashes) a solution.

I put down my textures and lightning to low even though I have a really good CPU, and I took out Post Processing.
