When I get close to the refugee center I found, the game crashes, and if I look in the debug.log file, I find a bunch of these:
15:48:41.672 MAP : src/map.cpp:6801: Empty locations for group GROUP_SEWER at uniform submap 6,9,-3 global 978,3501,-3
The numbers on the beginning and end are different, of course. I’ve tried it several times, and that always happens, so I guessed that there simply wasn’t a special pump-station town to generate the GROUP_SEWER in, but when I loaded up the game again and tried leaving the area, I accidentally found one … quite close by.
I explored around a little more, then saved and tried going to the refugee center again, and it crashed again, but there were a lot fewer of the crash messages this time.
I decided to just go on and ignore that refugee center.
Then, I found another one, and it happens there, too. :-/
Anyway, I’ll try to get the save uploaded some evening this week. And I saved a copy of the save file right next to the first refugee center, so I’ll throw them both up, I guess.
