[main/FATAL] [net.minecraftforge.fml.loading.RuntimeDistCleaner/DISTXFORM]: Attempted to load class net/minecraft/client/renderer/entity/EntityRenderer for invalid dist DEDICATED_SERVER
this error keeps on popping up when the server crashes, but I have no idea what it means
Can you share your log? Some mod is trying to load something that doesn't exist on servers
Ok apparently that wasn't the issue after all, the mod pattysmorestuff is causing the issue, try to remove it
Update: It worked! The server wide error probably happened when I was starting it, causing it to crash. The server crashed again, but it was easy to find out which one broke. Thanks!
