• Other mods that were running when the crash happened:

I was looking through your modlist and noticed that you have Infernal Expansion Version 1.3 installed. Are you trying to run a server with both the old release and the new beta installed at the same time?
Also, Is this a normal server or are you running it with something like Mohist?

The Infernal Expansion Version 1.3 file in the picture was from the old folder before I installed new beta file. I removed that old file when I installed the new one. So i've not tried to run with both files.
Yeah, I'm using Mohist !

Ok. This is a problem with Mohist. See Issue #158. I believe they are working on a solution to it, but this is on their side and there's nothing we can do. MohistMC/Mohist#1570 This is the issue where it is discussed. It appears they resolved it, so you may need to download a new version. Closing since this isn't on our side and is a duplicate issue.
