-For some reason that I really, really, really can't find: sometimes the Open Doors function (E) doesn't engage and you just can't open any door throughout the game. Temp solution: Restart the game when that happens.
-Sometimes a Covid will get stuck UNDER the map. I did a huge cleanup of the NavMesh so that doesn't happen anymore but it could still happen. I'm just one dude, guys. Gimme a break. That said, if you go far away enough from the stuck Covid, it will despawn and respawn correctly. If that doesn't work and you want to restart the game and keep your score, you can go near the fireplace and let yourself get killed. It's a weird workaround I know, but it works for now.
-Control Remapping: A friend of mine tried to remap the controls in the Menu and ended up messing up the whole thing. I tried on my machine and it worked fine. Not sure what's causing this.
