FF and others are still not allowing people to enter. I swear, it's not too dangerous to enter, we will be fine, let us in.
I've just tried on Xegony. I got a task in TBL, I waited 5 minutes and attempted to zone in but got the "A strange magic presence prevents you from entering....." message. I haven't tested other expansions yet.
So I tested a COTF, EOK instanced, and they both worked. I went back to FF and it also worked! Seems like someone fed the hamster!
