I run a dedicated modded server on 1.19.2. We had the Horde mod but had to remove due to it crashing with this error randomly after zombies attacked a player. We were unable to verify if there was a vindicator around due to the immediate crash upon login but believe there was one around.

After removing it, the server was able to run again successfully with no issues. Atlas Lib and Hordes were up to day and installed at the same time on the server and clients (5 players).

Willing to provide any details you need, thanks.

Should be fixed as of version 1.19.2-1.1.5d.jar,
Be sure to use this version as the 1.19.3 version won't work with your server.

Thank you!
