[1.0.12] Bughouse bugged out?

[WCG]

I've had this bughouse in my base for a long time with no problems. In fact, I have two in my base. No problem with that one or with any of the other buildings yet, although Kenshi crashes on me fairly often (reported here every time it happens).

But all of a sudden, my guys couldn't enter this one bughouse, and the person inside couldn't leave it. (I had her stand by the door and get someone else outside to pick her up. That got her out, but wouldn't get anyone else inside.) I hadn't made any recent changes, either.

I tried Ctrl-Shift-F11, and it supposedly found a problem somewhere, but it didn't fix THIS problem.

I got out of the game and checked the local files on Steam. (There is always a file or two - rarely, three - it finds problematic, for some reason.) Then I imported into a new game. I think that's all I did, and it fixed the problem, but only temporarily.

Now - after a very short time - it's back, and that solution doesn't work. Ctrl-Shift-F11 does nothing. The "fix" button in the editor does something to 8 buildings, supposedly, but it doesn't fix this. (When I try again, it just tells me there are no problems.) I tried using the editor to move the building, slightly (too much causes more problems than I started with). Nope. Nothing works.

There's a lot inside the building, but since I can't get to it, I figured I'd just dismantle the whole building and everything in it and rebuild using the editor. Just in case it was something to do with the bughouse specifically, I put a longhouse there, instead.

Note that I've never used the editor before (except to mess around with it in other ways, trying to fix this very problem; but I reloaded the save before continuing with this). Unfortunately, after I used the editor to construct the building and place beds and such on the ground floor, it turned out that I couldn't put anything on the roof of the building, and my guys wouldn't even use the stairs to go up there! If I clicked on the roof, they'd just run to the place on the ground floor that was underneath it.

And on the ground floor, they ignored the door completely and just walked through the walls to wherever they wanted to go. Funny, huh?

I've never used the editor before, but it certainly didn't seem to work for me. Is there something I'm missing?

Anyway, I've got nearly a thousand hours in Kenshi, and I love the game. I still get regular crashes. (I didn't, however, have a crash immediately before this issue started. I don't think so, at least.)

And yeah, I can just dismantle the building and lose everything inside it, then rebuild everything the regular way. That's not a big deal, really. But,... then what? Will this problem happen again? I'd feel a lot more comfortable if I knew why this was happening.

Is it just the bughouse? If so, I'll stop building them. (My second bughouse has our kitchen and all of our food. That would be a much bigger problem if I lost it. So I might want to move everything now and replace the building afterwards. But,... on speculation?)

I did see that other people have had this same problem with the bughouse, but, of course, it's easy to search for "bughouse." So maybe it's not just this particular building? I really don't know.

PS. I can't attach the zipped save game folder. It's too big, apparently.
