/tc and /nc don't work. Pretty sure this is because Herochat hasn't updated, and this is in no way your fault. Whenever you switch worlds, you are taken out of whatever channel you're in, and put into some other channel. For example, I was in a conversation with North_Korean, and he TP'd to a different world. He landed in global chat. I warped too, and I got put in local. If there are any more bugs, post them please.
