The two or three times I've had this happen to me it's occurred at the end of a match & I haven't been redropped. But I have experienced it.
My favourite glitch so far is when the Dropship Pilot forgets to actually drop me off. He remembers & we have to swing back around, but it sure is fun to overfly the enemy drop zone.
Then of course there's the classic "no-dropship" issue, where I'm either floating among the stars, doomed to a terrifying & crushingly lonely, slow expiration as either my mech cools beyond a survivable temperature or the o2 runs out. Either way, discombobulating to say the least!
Still. Loving the drops on QP maps, just thought I'd tack on to your experiences with some of my own
