I'm not sure if I missed something in the patch notes, but Gateway seems to be despawning if I run ~100 yards from either end of it. Obviously wasn't the case last tier (Ta'yak, for the SECOND half of the run, for example, but also on Empress and other fights)... but tonight on Iron Qon, both my portal, and that of the other warlock, were vanishing (despawning, far end first) if we moved too close to the boss's spawn area (~100y from portal exit). We were completely baffled until we saw the TIME at which they despawned (finally, once out of combat rather than in).
Was this an intended mechanic I should've known about, something that was unintentionally changed, a bug specific to Iron Qon, or am I just going crazy? It only contributed to 1 wipe when 2 healers got tornado'd (so spoiled, those healers, right? I'M SO SORRY PLEASE KEEP HEALING ME) in the second phase, but I'd really like to know its new limitations, so I can plan around them better.
