I have found a really weird bug and I am not exactly sure where it came from. I went into Natasha's cabin after I rescued her with her, looked around then went to lake view to try and complete the Quest leading to Serena, but at this point I noticed I couldn't interact with my weapons at all. Couldn't manually change them from the Menu, Couldn't quick change them with the W key, couldn't fire them with the Q key. Could still take damage from the Zombies. Fortunately I had saved before entering the Botanical Gardens so I went back to the base camp and it resolved the issue, temporarily. I died in the flower puzzle and when I loaded the issue was back. I had the Crossbow, Pistol, and several Medical Herbs and one first aid kit. As this severely impacts game play I was hoping someone had a more permanent fix than restart my game file.
