I bought my house plot in the player housing zone and when i placed my cottage on the housing plot it has become "attached / over lapping" with another cottage. I can still enter my property ok and use all the hook points in side as required, but when went to add a porch to the property this did not show up. It looks like the wall where it should appear is the wall that is "attached/over lapping" to the property next door. My plot number is 336
