Hi All,
Just come across a random hobbit house in the legacy version which had generated without a roof.
Seed is 1644423361786782520.
While it is very close to another house (one directly behind it) and I have seen instances of some structures damaging other structures before simply due to generation proximity, there doesn't seem to be any indication that that has caused the lack of roof generation on this one specific house (there is still space to walk between the 2 houses).
This is the first time I've seen this happen in all the number of worlds I've created (which is a lot), so it is a very rare instance (maybe even just a one off).
Just thought I'd report it here for awareness, in case it needs to be looked into (I don't necessarily expect at this stage in legacy version for such an evidently rare occurrence to be looked into while development for the new version is taking place!)
