Possible survivor glitch?

[Kommando]

I found out yesterday I think Tonya Waters may be bugged. I saved her and Ross and decided to give her an SMG. After which I picked up Ross and she laughed and shot both of us. I tried picking him up again and she laughed and shot us again. 3rd attempt same thing. I have her a handgun and she took off like normal. Can anyone else confirm this or maybe mine was a random bug?

I also ran into an issue with the 3 survivors in the gun store. The guy ran up to me and started talking but I couldn't seem to talk back and when I walked in the other fired on him and me. I reloaded a previous save and it worked like normal.
