➀ Setup hasn't changed afaik, but I'm getting crashes on a save in last few days of summer when it didn't used to when viewing the surface without civilian alert calling dwarves off it, as well as the copy of that save from day before.
➁ I'm getting lot more
sharpnel when switching screens; something that previously only happened with dwarfmonitor overlays.
Were that all, it's not hard to imagine blaming save/hdd corruption for first, especially given the crash doesn't happen 100% of time so I could have just gotten lucky. It's easy to imagine me not noticing second happening as much previously. It's easy to imagine that I accidentally introduced a bug; TWBT & stability issues aren't unusual pairing, and methodically searching what job or situation causes a crash ought to be possible. However....
➂ One of the features I added to TWBT was BUILDING_TILE_ONLY flag for overrides. It seems like now those overrides are never applied when flag is present. The problem with this:
I keep backups of old compiles of TWBT. The issue is present 15th Dec backup, with no modifications since 9th according to OS. And on dfma map made on 19th Dec, the screenshots clearly show them working as expected.
