Hey, My spongeforge 1.12.2 server crashes whenever a player places and fuels a furnace. crash-report: https://pastebin.com/Zd4RGBdM Thanks in advance! Edit: SOLVED: It seems that the mod "_MixinBootstrap-1.1.0.jar" was causing the issue. Solution: renaming the mod to "zzzz_MixinBootstrap-1.1.0.jar" (thus, making it load after Spongeforge?) [another solution would probably be to remove the mod completely.] In general, It seems like any mod related to Mixins should either be loaded after Spongeforge or not be loaded at all.
