Game mode: Online official Type of issue: Bug Server type: PvE Region: Europe
I have to use foundation blocks due to environment. And a horse stable placed on foundation blocks is too high, the first step is so high that impossible to run up, only jump. And looking badly. And impossible to build lower. Looked like there is something wrong.
Build foundation with foundation blocks and place a horse stable upon.
You can reduce the height of an object you are trying to place by holding down the shift key and scrolling your mouse wheel up/down to adjust its height. That might work for you.
FYI: alt and control also adjust angles, too, when placing objects.
