Got the same issue myself just now when testing Modular Buildings Redux, had started writing up a report before I tried a different search and found this thread. In my case I was trying to build next to an existing structure, so I got an error message rather than a misplaced building. So I'll just go ahead and merge my post with this one.
What did you do?
Tried to place a steam engine where the game indicated one was buildable, above another steam engine.
What happened?
The game popped up the error message that the steam engine was in the way.
What did you expect to happen?
For the steam engine to be built, as it was not shown to be colliding with anything, and should not be colliding with anything as the placement clearly indicates it to be above the other steam engine.
Once, always, or sometimes?
Not often, but it is repeatable - it seems to need pixel perfect precision, which I got by turning my mouse sensitivity down. Confirmed with steam engines, steam turbines, substations, and express splitters. I was able to reproduce it when building on the right side of an existing steam turbine, but not below or to the left.
With an express belt, it gets weirder as when the mouse is pressed, the building preview suddenly jumps down one tile onto the already placed belt. If you hold the mouse button down, it stays in the lower square, and moves back up when released. This did not happen with the larger entities. At least once when testing the belt was built to the left of the square that was indicated.
Could not reproduce with steel chests.
