Hey there, thanks for making a help request.
If the error ever happens again, if it's something in game then screenshot it, if you opcode then get the crash report.
Although this may not happen on other servers, it can be due to our code or mapping or something to do with a mod. So the helpers were just following the usual diagnostics by asking you to uninstall mods as usually this fixes it.
If the problem persists, please make another help request.
Meyrick,
