so we built up in a giant red sheet metal building. and built 3 watchtowers in a row touching so the wall could be blocked off and players can't jump in. so we built the first tower and then last tower but the middle wont build not with all needed materials. its in front of a metal beam so i'm guessing the collision is into the tower and the tower into the beam. making not being able to build. meaning the wall or tower cant be built super close like we used to build em anymore. we built this same setup days before the update so it worked just fine.
