Is it a "known issue" that if a building's footprint is the same as the plot size, you're not allowed to place it? Here's my example:

Last night, I rejoiced in finding and buying a 50x50 Residential plot. Good times. So, I tried to place a Tier 4 Guildhouse on the plot, only to be denied. I looked up the size of the guildhouse, and sure enough, it's 50x50. It should fit snugly on the plot, right? It certainly seems odd to me that I should be allowed to select a building from the menu that won't fit on the plot, given that on my old smaller plot many larger buildings were unavailable because of their size. Has this happened to other people, and if it is a known bug any idea on when it might be fixed? (a guy can hope...)
