Successful Legend Onslaught run today (post-patch) against Hive on Vostok. Wave 49 we get a Tormentor. We get the Tormentor aggroed onto a Shaxx dummy and then deal with the rest of the wave, mostly ignoring it. After rest of the wave, killed tormentor, it said "Wave 50, go through the portal" but portal didnt spawn. I then tried killing myself and ressing myself after the 30 second timer, and that spawned me on the ship, but even after all 3 of us did that the rally flag market didnt appear and the 3 "doorknobs" didnt spawn, so we couldnt enter the boss room. One maybe relavent detail: That wave we also had hive shriekers. I tethered under one of them so it closed up for a lot of the round, and while we killed 2 shriekers on the other side of the area, we only killed the one on the tethered side, pretty sure a 2nd never spawned after the tether - wondering if no 2nd shrieker on that side tricked the portal-spawning mechanism into thinking the wave wasnt over? Absolutely devastating to get an hour in only to have the game brick us from finishing the run.
