dd3+ crashing combining paths
I am attempting to create curved hallsways on my map. I create arc lengths from the edge of a previous hallway to the room i want to connect to, then convert these lines to paths. But when I attempt to combine these paths, when I hit enter, cc3 crashes. I've rebooted, i've redrawn them from scratch, I can't get this to work and I don't understand why? I've created custom rooms before, including on this map (circular room at one end). Any idea what's causing this crash?
