ULTIMATUM CRASHES CONSTANTLY

Normal and inscribed ultiamtums are crashing every single time you get stone circles to stand in. Even if you somehow get to finish it, running an inscribed stone circle version is ALWAYS crashing.

I've lost almost 20d+ just crashing and not being able to finish. There seems to be a good majority of players facing this issue and its not a specific bug. Please FIX this IMMEDIATELY.
