Still happening today, a friend of mine was trying to get the achi to explore maldraxxus, was using a sandstone drake and I was checking onboard if something was missed, we got in there and as neither of us had the necrolord portal unlocked, we couldn’t leave.
Unless there’s a massive amount of people reporting a bug, it will never get fixed, I’ve seen this happen even for squishes done wrong, such as abilities supposed to reduce your attack power by 20% that because of squish reduced your attack power to 0, they lasted years.
