Near the end with Caroline there is a cutscene after the boss fight where you would switch over to your gun and cannot switch to other weapons nor can you fire you gun after 6 shots even if you have ammo in your inventory. Also any exploration the next morning with any character will have a minor bug where when you return to base, the characters would go into the barricade and come back out instead of going into base and advance to midday. And some parts of the flower room you can still go into some walls on the top right of the map.
