Have a look at the above error. Seems to be an issue with argument parsing.

Have you modified your chat messages in the config? My guess right now would be that a is missing from a message string

[nkomarn]

I just realized I left important information out of the top. The thing that prompted the error was:
[16:20:14 INFO]: (player) issued server command: /pvp off\

So I think the issue is just the \ is acting like an escape character and thus the error occurs because there is nothing to be escaped.

Ah, yep. I'm really busy at the minute but I'm working on a new version I hope to have done fairly soon. I'll make sure this is fixed in it. Thanks!
