[Edit: Just realised I shouldn't ask about old versions, just ignore this post or delete if you're a mod please. Thank you.] Hi, I'm hoping someone might know what the issue with my game is. So I loaded up an old world from a couple of years ago with exactly the same mods now as then and exactly the same version. I could place any item from these mods a couple of years ago and they didn't cause the game to crash. However, now, when I try to place a particular type of sign with this ZAWA mod, the game crashes. Here's the full crash report. Does anyone know what the issue could be here?
