I'm pretty sure one of my mods caused this, but I don't know which one. Removing sight gui fixed the crashing

The same exact thing happened to me. I came here hoping that someone would've found it already but no luck. Simply removing the mod just fixed it.

The Stendhal mod is incompatible with SGM, if you don’t have it try removing every mod that changes the chat and adding them back one by one
