Additional context

It's not a crash but it prevents the game from working.
I know that the log may not make sense, but it only happens with Iris 1.3.0, in previous versions or without Iris the game works normally.

Already fixed in main branch; Mod is using invalid characters and assuming an exception.

Using Iris 1.3.1

@IMS212 I compiled a version without path validation, NBT error continues, is not the same error.

We are aware, and are discussing on our Discord. Please do not provide updates here, as we are already aware of the core issue.

Should be fixed with 1.3.1.
