Hi there!

Tried building stuff underground but looks like wooden support hitbox is very inaccurate in most of the cases and even one single happened to generate multiple hitboxes. Is that intended or that is a bug?

I made a blueprint that had wooden supports, when I placed it apparently support lamp ghost got generated in weird places.
I tried removing the ghost wooden supports with the entire building but "support lamp" is still there blocking buildings placement.
For testing purposes I started placing wooden supports and removing them. This ended up generating even more invisible "support lamps" that made the thing even worse.

I had this same issue but i noticed i could get rid of the ghost hitboxes with an aai mining vehicle

The blue hitboxes indicate machines that get their power from this electric pole.
The one hitbox near the support is the support lamp. I'll move it to be aligned
