So. I'm not sure if this has been answered, I flicked through to find out, but haven't found a solution. I made my first map two days ago of Moria and Lothlorien and liked it, but decided to remake it today this time using some of the Moria props, those of which being the Great Hall flooring, walls, pillars etc. Unfortunately, I cannot actually seem to build on most of these, but on one or two spots I can. The land undearneath the spots are flat and underneath so I am rather confused as to why one or two of the "Floor" square things can have buildings on them but others won't allow it. Any help would be much appreciated.
*Edit*
As an update: I tried removing a pillar, floor and the corner of a section, I was able to build there, I am pretty sure it's the wall, but where I built "Dwarrowdelf" I still cannot seem to build in that area in general. Is there a way I can make it so I can still build there or something? Really hoping to get this going, I do intend to get into map making as I've killed the last 3 days just tweaking and playing the first draft of this map.
*Edit 2*
Another update: I replaced a hall with another wall set "Nofade" or something, not sure on the difference between them, I'm new to mapping so that's to be expected. I am now able to build in that area fine, I did the same in "Dwarrowdelf" however still got nothing, I removed walls altogether, still hardly anything, I removed all of the hall and was able to place buildings in a few locations, (I do use Shift I and know that there is no "Impassible" terrain that I placed by accident). Not quite sure if I have slipped up some point, the area is all the same flat level and still having some trouble. If anyone can help, again it would be much appreciated
