I've struck a zone on one of my factory floors where, if I try to build something, it's hologram sits not on the ground (Foundation block), but rather, in the air above it. The distance it hovers is about the height of a 8x4 foundation block. If I build another foundation block on top of the existing level, or even destroy my existing top layer(s) of foundations, the construction I want to build still hovers about 4m above whatever the currant floor level is.
I have a feeling that maybe the terrain might've changed with an update and that's somehow screwed up my floor parameters. Not too far from where this problem is happening, there's a Bacon Andgarlic mushroom hovering in mid-air, about 20-30m above the ground.
It's possible that I have foundation blocks burried beneath the currant ground level that I can't see. I'd like to be able to delete all my foundations in the effected zone as an attempt to 'reset' the problem, but obviously, if I can't see a foundation, I can't delete it. Does anyone know of a way you can see through terrain to check for foundations and delete them?
