It looks like my problems aren’t over yet. After updating to the latest version of Quark, my game no longer freezes when creating new worlds; however, my game crashes now:
java.lang.NullPointerException: Exception in server tick loop

Full crash report: https://pastebin.com/raw/TbZMRTGf

My game doesn’t crash or freeze with only Skygrid installed or with Skygrid and only a few mods installed. However, I have over 300 mods installed. Skygrid seems to be conflicting with one of them. I hope you can gather some information from the crash report that can help you figure out what mod is conflicting with Skygrid.

Versions

• Minecraft: 1.12.2
• Forge: 14.23.5.2816
• Skygrid: 1.4 (latest)

Looks like a rather simple bug, should be fixed very soon

I will upload a working version (1.4.1) which will catch these error and log them.
If you could test it and send me the log it would be very helpful.

it did this with just jei optifine jornymap and tektopia mods on forge
