just placed 7 of them , one next to each other.
only 3 got built, with a 2x2 area each
4 of them are missing. can't find them in star.
it looks like they still haven't fixed their placement issue. 1x1 when you place it to be built, 2x2 when it's finished or try to move them
gonna see in the morning if the other 4 are coming back or not.
EDIT:
well, there's a trick to it by the looks of it
i could only line them all up while they were being built.
when i've tried to place new ones next to already built ones, they were taking 2x2 space
