It seems to be only happening on a single map, we're able to connect on different ones? Not sure how.

The mod Even Distribution (2.0.2) caused a non-recoverable error.

We have the same issue on our server. It crashes the server:

Same issue, it was actually working fine throughout our playthrough until we had a new person join the server. Since then we can't get it running again. Tried uninstalling and re-installing from the server and now the server won't start at all with it enabled. Ours has similar logs, but says "Filter conflicts with filer in slot 11" rather than the numbers people posted above. Did anyone get it working again after having this issue?
