Default setting for S:scheduledTaskExceptionAction=WARNING_SCREEN, which crashes servers

When running VanillaFix on the server, it will occasionally cause a crash due to trying to load a GUI on the server (the welcome screen).

VanillaFix tried to show a GUI on the server, got java.lang.NoClassDefFoundError: net/minecraft/client/gui/GuiScreen

Full crash log

Possible Solution

Either A) the default setting should be LOG, or B) the mod should check which side it is on (client/server) before attempting to show a GUI (and preferably fall back to another method)

You can check coremods in the crash report. I also don’t think we add any coremods not part of ATM3 that even access GuiScreen other than VanillaFix. Also no, we don’t have more than one version, wouldn’t that likely crash all the time instead of specifically on a certain config setting only, and only when reporting errors?

That being said, after half a dozen crashes this morning because we accidentally ran the default config for a bit, we can confidently state that it is indeed VanillaFix with the default setting of notification causing this crash. Again, the crashes look identical so I won’t post new reports.

@nullKomplex With the same error? That’s rather odd…thanks for testing though. Rune and I are still trying to figure out a good way to fix this.
