Ever since I stopped using Workshop Rearranged because it caused crashes, I noticed that interior plots have hard time fitting in self built structures. I noticed that as long as I have not built a wall part the plot snaps to floor easily. If the wall is already built plot usually wont go even near the wall without going red. When I place the plot on floor I cannot place the wall piece to where the ASAM sensor is because it is on the way. I can place wall everywhere else without problem. I guess the wall part or ASAM part needs to be taken slightly inwards to remedy this situation. I have currently no other workshop mods in use that affect the workshop parts.
