I got to wondering this as there seems to be a delay between building stuff and it becoming visible. I was waiting for my rail track to show up, also for the small volcano at -114,28 to vanish?
Seems to update map tiles at restart.
That makes sense, but presumably player locations are realtime?
I was wondering this myself. Thanks guys!
Seems to be updating faster now? I can already see the grassland I put down last night and the cactus I planted at "zombie ambush corner".
