I tried to get a OOSLog for Infernals but it didn't generate one. I have logging turned on in BUG. Not sure why the Kuriotates save generates a log and my infernal save doesn't. Here is a save file to quickly generate oos. Interestingly I also got an oos error when Calabim took over an Infernal city, but I wasn't able to reproduce this when I tried a second time. The infernal capture errors is easy to reproduce though. After you select "I'll manage the city" (don't raze it or inspect) then it creates the oos right away.
