Finishing this stupid shit without wasting my MP pots took me around 2 fcking hours -.-
I got tped into the same place with my 2 friends.. we couldn't see each other / trade / party but when i attacked a monster they both saw it's HP going down..
I think there are certian places that if u cross them, you get tped into jail.
Both times happend while i was running from Karus's lower deruvish spot to Linate (there's a place in the mountain that is lower and u can go through)
I have seen 3 ppl in here that said it happend to them near luf castle like hoDoo

If it happend to anyone else at another spot write it here.. we should list this shit
