Another frustrating one that I’ve seen is the inability to snap in a ceiling tile at the base of steps when building downward from above. I wonder if glitches like this have shown up as a result of the devs trying to squash exploits or some such.
I’m just happy the stair corners work properly though. I believe @Multigun was instrumental in tracking down the blueprint/socket issues on those, wonder if they could see any similar anomalies with the roof corner/door frame or stair-base/ceiling socket interactions…
