Details of the issue We are only playing 2 people on the server, and it all of a sudden started crashing randomly and very often. We start it up, and within 10 minutes it would crash.

I've linked the most recent crash and tried google'ing the issue, but can't find any solutions. Please help

The crash is due to a ConcurrentModificationException. This usually means that something else is trying to access the same files the server is using. So you may want to look at your AV scanner and put in an exception to make sure it doesn't try to live scan the folders used for the server.

I don't have an active AV. the only thing i can think of is that im running the server and playing the game on the same pc, but those shouldn't conflict like that at all.

Actually no. That exception is thrown when data structure is used misused. See https://docs.oracle.com/javase/7/docs/api/java/util/ConcurrentModificationException.html for references.
