Random in the middle of the day, CTD. I can't seem to find what the minions are doing that is causing it, but it is very very repeatable and this is the DMP that it generates.
RIP day 73 food/water/power sufficient colony =(
There is nothing special happening.... minions are just going about digging, and taking slime to the algae makers, running on the generators... then... *boom* CTD. Reload, change some minion orders... CTD. Rinse... repeat.
