I am having a very similar issue. I have tried multiple different things to eliminate other possibilities but every time I try to delete a wall in build mode the game freezes and I can't do anything ...
Ideas
Hello! Same thing happens to me. I keep trying to build but whenever I try to delete half walls my game just freezes up. The screen will say "paused" even when I click play. Also happens when I place full walls. I play with no mods/cc.
