Just had a go at the new build. I had massive lag multiple times I managed to place 3 banners before the game recognised the 1st one.
I restarted a couple times decided to play longer this time, I triggered the goblin invasion which started off correctly, how ever while placing down my beds it managed to create a error. After that the goblin camp duplicated and I ended up with 4 Warchiefs half made buildings, weapons that are used by the goblins being placed on the floor instead off there hands.
It ended up with a crash before I could make screens to be posted.
Hope that even can result in something helpful with no further screens shots or saved file.
