Readjusted several spots and windows where heartlings get bugged A LOT when building. I tried to make the houses as small as possible without bugging them every new save.
I even reduced the amount of crates and windows.
T1 storage and big animal shed are now small version.
Carpenter lv 1 now can make tiny and duo houses, you just need wood. Any workshop buildings however, need lv 3 carpenter to make supply shelf.

Changes:

Removed several problems like blocked path to stations, missing some ace stations, too much windows, useless unnecessary extra work shelves and racks, most replaced for crates.
Adjusted some roofs and blocks, heights and sizes.
Some buildings that now I consider not as Tier 1 were removed.

oficial version 1 with all T1 included
