Post your playable Crush the Castle 2 maps. There are other threads for talking about CtC2. If it's not good for shooting at or interesting to look at don't put it here: NO castles that fall apart by themselves, NO random junk piles.
I should have called it unfinished castle. I was adding all these nice wood beams and I was going to build stairs, turrets, etc, then it started lagging so badly that I quit adding stuff. xD
I see why it lagged. You got stuff stuck between foundation elements and because of the size issue, they are trying to get out! One thing you can do is undo the foundations, let the castle settle and then reset them back.
