Right, so it’s what I thought it was.
Basically, there isn’t anything broken here, it’s working as it has been designed. When a ceiling socket attaches to what, we the players, see as 2 Pillars, systematically it’s connecting to one. I don’t know how it “chooses” one or the other in this scenario (I’ll have to do some experimenting to see if I can figure it out). Obviously you intend for it to attach to the one with the higher value, the system wants you to connect to the lower value for x,y,z reasons.
Maybe it would be better for the stability system to instead add the two components together up to a maximum of 100. Or maybe not, because I have a feeling that would break PvP (from a builders perspective, seems like a good idea to me heh heh).
Alternatively, when the system detects it can connect/snap to more then 1 socket, have the socket choose the one with the higher stability value. Though I’m not a coder, so, who knows if that is possible without redesigning how the stability system is coded now.
It has been this way for a long time though, many months at minimum. When I was working on restoring stability to the decorative beams in my LBPR - Collision Improvement Add-On Mod, I spent a stupid amount of time trying to get them to work and discovered what you are just now discovering for yourself. Not sure if there is any way around it without doing all of the steps you took already (destroying stuff), but I’ll play around with it.
