Don't you just hate having to log completely out, and then back in to change to a different character on your account?

Yeah, I hate it too.

So, instead, try this: [changecharacter <charname>

Enjoy!

(just put script somewhere in your scripts folder and restart server)






For the 2 users getting Null Reference Exceptions, I recommend modifying the code slightly to try and trap the error. Something like this
