Not sure if this is something my party was doing wrong, but just in case I am going to report it as a bug (Hope I got the right section). Whenever we would try to do the KPQ it would randomly warp us to the exit. It did this periodically (about 5 times) and we were only able to finish the quest once before we gave up. If this but is already known or there is a fix to it then disregard this post (I'm fairly new so I wouldn't know). Thanks! *update: I didn't notice there was a bug section oopsie!*
Its usually glitches(I've Noticed) when someone is using a pet\certain skill\certain animation is glitching it. try take off pets and cc, remake party, i grinded like 10 pqs in a row without a glitch, just keep trying till you find out whats working for you.
Sometimes the best thing to do is just CC and remake party. There's no fix at the moment as we are busy focusing on the New Source :s
