The Single Portal for the Admiral Fight is Still a Problem

Just lost my first ship during the Admiral fight because the game totally froze up. I waited several minutes expecting a disconnect and eventually just closed my client. Fortunately for me, I've just been doing small shipments, but if this had been a big 50M boat it's tough to imagine how terrible that would feel. If I had just lost a portal to this, no big deal. But losing access entirely seems unfair for something I couldn't control.

Kingsmarch stability had actually been pretty great up until the last week or so, now it seems a quarter of the time when I zone in, it's unbearably laggy. I assume the Admiral's arena is tied to this instance and is why I experienced my d/c.

Yup, it's just bad game design. In theory it's great, but in PoE1 the game crashes constantly with no rational explanation or tutorials on how to prevent it. So doing 1 portal only content is just bad design.
