Co-op ascendancy buggy as hell - PC

We were running a co-op in Sekhema, leaving the boss room - room cleared, loot collected. One of us suddenly died, no damage taken. That was the first WTF moment. The next WTF moment was that the dead player couldn’t respawn anywhere, no option appeared (I’m not counting the ESC menu). The remaining player could only move around, they couldn’t buy anything from merchants, couldn’t pick up loot, and had no teleport options. Everything was blocked and everything was bugged. The dead player could only exit through the ESC menu, for example to Character Selection (or quit the game). Even that didn’t unlock the surviving player (dissolving the co-op was of course the first thing we tried). Basically, the only option was to restart the game. After that, only one player could start a solo Trial, the other couldn’t. The game had to be closed and restarted several times.

When bugs like this happen in co-op on maps, it is meh but okey, but that Trial, which is annoyingly long, was very unpleasant.
