Problem Description

I didn't start getting this error until today (been running the server for a few weeks), have no idea what might have caused it.

Duplicate of #246. Please use build 35 from our Jenkins build server.

A new version with the patch for this will be released soon, we are just finishing some 1.13 compatibility updates to better integrate with 1.13+.
