java.lang.Thread.run(Thread.java:748) [?:1.8.0_151] Full log is there: https://paste.ubuntu.com/p/T9pHWG4FrY/ (couldn't use pastebin because of its size) I'm running forge-1.12.2-14.23.3.2688 installed via the installer. My java version is OpenJDK Runtime Environment (build 1.8.0_151-8u151-b12-0ubuntu0.17.04.2-b12) I would be able to identify the culprit if it would state which mod might be related to that but it doesn't and as for the "internals" I have no idea whare to start. Google wasn't really helpful here too. Please help me to identify the issue so I can fix it. regards, dura-zell
