Well, I waited until November, and journeyed to the Fruit Tree Exclusion Zone. As I'd hoped, the game didn't crash this time. After a bit of searching, I found this spot. There's a mature pink apple and a young pink apple growing very close to each other, flanked by a maple and an oak. They still had some leaves on, but whatever was causing the problem wasn't there. I chopped down both the apple trees. Of course, I won't know if that fixed the issue until next summer, but I have a good feeling about this.

That's interesting. If it's the leaves specifically that are causing the crash, I should be able to go to the crash zone in winter, find the fruit trees and chop them down to quick-fix the issue, right? Assuming it's even the same problem, of course. And yeah, I'm in a temperate zone. The only mods I got are a spyglass and a player corpse, and I don't see why either of those should have any reason to affect mapgen.

I'm having the same issue (crash in a specific area, NullReferenceException with something to do with fruit trees), and it also seems to crash in repair mode. Any other clever tricks to try?
