Yesterday I was getting warped out of the halls doorway in Sardon's for just standing in it (which is something that literally every guild does). I wasn't getting warped to the lobby, but to Sister Gertrude's. Not sure if it's this script behaving funny or just an admin not knowing what they're doing.
Hope you manage to refine this though. I've seen this work a few times, and it seems to take 5-8 seconds to trigger the warp. It might be better to lower that, but I'm sure that causes some annoying side problems. Would be a huge relief if lag blocking and other annoying tower glitches could be resolved through code.
