Sorry about never following up. It started working again, but I just re-tested on the latest extended launch and it appears to be still crashing. Now it happens after the map renders, but a few seconds after trying to move the map around.
I also left out and important step - on this heightmap i also set the water level to -2 which I think has an impact of this bug (because at the default -5 the map seems to work fine)
It also can occasionally just crash without warning. A generally unstable map, it seems.
I have split this from the other topic because this appears to be a different issue: a crash during map generation will inevitably be in a different part of the code than a crash after map generation. If this occurs after map generation, can you send me a saved game of the unstable map? Also, did the crash occur when zooming in/out, by any chance? If so, can you re-test with the latest nightly executable build, which fixes a crash in those circumstances for some users?
Thank you for flagging the nightly builds. It appears to be working much better now, and plays stable enough to load the map and start a few schedules/routes. I will follow up with a new bug report & information if anything new occurs.
Excellent, thank you.
