I've been building my Iron Titan and it was going very well. I know this because I constantly used NBTExplorer to make sure every village had the right amount of doors in the right position. Now I've encountered a problem that leaves me scratching my head. Once I start adding the 11 permanent doors on each side, and I get to the 3rd row of doors for each village (so I'm adding the 17th door to each village), the problem occurs.

No matter what I do, three of my villages simply don't pick up their 17th door. Using NBTExplorer, I see that every other village has 17 doors, but those three villages (which are in a row close to the center of the titan) only have 16 doors. If I keep adding doors like normal, the farm breaks and some villages get 32 doors while others get much less.

I've used a lot of backups and always get the same result, the only backup I haven't used is the one before I start placing any doors (although I don't think I even have it anymore and it'd take too long to reproduce).

Did anyone encounter this problem and know how to fix it? If nothing else works, I'll try to make the Titan a 29 village farm if that's possible, by removing those three rows of doors

EDIT: Also, I even manually added doors into the village using NBTExplorer (and I'm oretty sure I added the doors in the correct way) but it still broke
