The roof of some builds are not being generated correctly.

it is a new world, but i am thinking it has something to do with the saved files in the structure folder. So I am redoing each one that is messing up to see if it is a issue.

i will update you once i have the new files and try it.

I haven't found such bugs with 1.5. Was this world transferred from 1.4 to 1.5? Do these bugs still exist with a new 1.5 world or completely new 1.5 worldgen?

fixed it by redoing the ones that were messed up. idk what it was but redoing it fixed them

Strike that, I finished redoing all my structures again and I got almost all of them fixed, but i found the issue/problem. When a structure is up/down higher/lower then the structure next to it, It will sometimes not generate the bedrock the right way. Here is the new picture after I redid everything today.

Here is a link to my structure folder if this will help you out in any way.

I have just found that it is also doing it with the mods structures also if one of my structures generate next to it. but my structures bedrock spawns correctly.

I also found out that if I disable the roof in the config file all the walls spawn the right way. it will only mess up when the roof is turned on. I have also figured out that if i turn all my structures to a up 6 the roof generates the right way everywhere. but anything below that it messes all up.

I too am experiencing this weirdness.
