Bug Description

Game crash when creating a save due to shader compilation failure.

Steps to reproduce this issue:

1. load game
2. create a save
3. game crashes

Expected Behavior

you should make to the main menu

• Version: build-202106020756( 3884b8d)
• Last-known Working: Unknown

Seems very similar to #315 - please consider merging these issues into one.

[Triticum0]

I was going to but they crash for different reasons

I was going to but they crash for different reasons

I would just separate the logs for the games and combine both of them into the same issue post labelled “Games Crashing Due to Shader Compilation Errors” with both title links listed and your hw info, just to tidy up the issue area. As they are both pretty similar and linked to Shader Comp Errors

[Triticum0]

should i add it to #54?

[MasonT8198]

should i add it to #54?

I wouldn't, seems the shaders are different in the two issues, I would squash #315 into this one

[Triticum0]

ok squashed
