Reproducible CTD: Vehicle Creation?

Reproducible crash. No idea what’s causing it yet, I just need to spin some time in this game and it’ll fall over with this message.
Not sure if my save is completely screwed or not.

DEBUG    : Out of bounds add_vehicle t=none d=90 p=132,5,0
 
 FUNCTION : vehicle* map::add_vehicle(const vproto_id&, const tripoint&, int, int, int, bool)
 FILE     : src/mapgen.cpp
 LINE     : 6819

Then there’s the crash log.

Can provide a save repro if you want, but they’re huge so I’ll need someplace to dump it.

If no one has answered for 26 days, maybe you should consider contacting one of the devs. Nobody seems to know why this is happening.
