I urge anyone who questions even slightly, to go and try my theory out, by building lots of foundations and blocks just onto someone's cupboard build zone, and watch bits fall off their base.
I tried it with a friend last night, works every time. Doing it that way, proves that the stability has nothing to do with it, and if I'm wrong, please explain why, I have no problems admitting when I'm wrong..
Depending on the size of their base depends on how many foundations, blocks etc you need to set down, if it's a small base, you'll obviously need more. For this reason, I believe there is some kind of "limit" set to each persons "cupboard zone"?
Also, Grymthor, it seems to happen to floors and walls moreover ramps and blocks, they seem to stay fine in my builds.
That's whats mostly in my builds, Floors, how do you think i get the blocks and ramps to stay up. I dont disagree with you i have recently experienced what your talking about but that was AFTER i had built my rollercoaster and stairs in the same area. For some reason most of walls, doors ways refused to be placed despite having all necessary components to exist and this was only on the second floor, i dont think i had the problem until a recent update. I'd be happy to help you duplicate the same thing on Daves server.
