This issue keeps happening to me, and I was wondering if there's a fix to it? These are two walls, with this angle gap between them. Is there a column the right size to fit in there? Or am I out of luck?
If either of the walls are on the outside edge of the grid the sides won't join and other items like the roof don't fit as well. But if you rotate the wall or walls they will land on the inside bringing them together.
