Pretty heavily modded game, so I made a backup of the save in case you need it.

Thanks so much Xaal! I’d love to take a look at the save, that might be the quickest way to figure out what happened.

I’m away from the computer right now so can look in a few hours. Do you have a way to upload it somewhere?

Hopefully that works. Crash is ~30 seconds to a minute after loading the save.

Thanks! That was a huge help. The fix is posted to the mod portal.

It feels super weird loading someone else's save. Like finding yourself alone in another person's home or something. We play with a lot of the same mods, but you have a few I've never run across.

Technical details:
A furnace had earned a bunch of upgrade attempts due to how much work it's done. It hit legendary (the cap in this save) but still had upgrade attempts left. Most of the code handled this scenario (of being at max), but a small part didn't and I hadn't ran into this situation in testing. This would have happened to others that added the mod to an existing save, so I'm glad to catch it now.

Thanks again for the bug report! Please let me know if you find any other issues.

Thanks so much. And I'm testing out a ton of new mods with this run, so a lot of them are new to me too. (:
