I've noticed while trying to build, that there is a lot of "Location Obstructed" errors compared to the first game. It's making trying to make foundations for a base pretty difficult as well as making walls to go around it. With the inevitable addition of tower defense later down the road, if the restraints on where to built aren't eased up on, trying to build something near impregnable will be a lot harder.
While I can get adding more restraints on it, when people would box in the area under the oak tree in the first game basically putting that area on easy mode, the current restraints in the sequel seem too limiting.
