Seconded this. Had to remove the ConnectionMessage mod because it just kept giving errors.

also with any other mod that send notification to chat such as udderly up to date that send notif about server is restarting.
the error is this

function: GetMessageType -- file: ISChat.lua line # 1203 | MOD: Total Immersive Chat System
function: addLineInChat -- file: ISChat.lua line # 1237 | MOD: Total Immersive Chat System
function: addLineToChat -- file: utils.lua line # 99 | MOD: Player Connection Message
function: doConnect -- file: utils.lua line # 11 | MOD: Player Connection Message
function: onServerCommand -- file: MainClient.lua line # 7 | MOD: Player Connection Message
java.lang.RuntimeException: Object tried to call nil in GetMessageType
at se.krka.kahlua.vm.KahluaUtil.fail(KahluaUtil.java:82)

also having this issue with player connection msg, udderly up to date, afk mods. udderly up to date in particular is kind of a dangerous one to have issues with

still hoping for a fix too

A lot of mods create a fake Java message object but, by laziness, do not implement all of its methods. That means I need to check for malformed objects in my code to support them.

I pushed a new update that checks one method that seems to be usually missing. It will probably fix the issue for some of those mods.

If a mod is sending a malformed message object and I manage to detect it then the message will be shown in chat as an info message.
