This save crashes reliably about a minute or three after unpausing.

It might be related to the squads (the station order seems to crash the game immediately if I cancel it), or to the tile that's queued for channeling, or whatever else the other creatures in the caverns are doing. I'm at my wits' end, I have to say.

In case it helps: I play the game on Windows, and in windowed mode (since that makes it easier to tab in and out for chatting, pausing/resuming podcasts & checking the wiki).
