Their are two problems really annoying me. first sometimes when I pick up a root or flower my gun disappears and then all of a sudden comes back out of nowhere. Also this happens alot when I am in sneak mode, I will just be walking and my gun disappears then a weird animation appears where it looks like my gun is above my head.(occurs in 1st person mode). Really annoying when I am trying to sneak up on something. Also some times I will be attacking a raider and when he/she gets down to one bar of health they just stop and stand there and seem not to take any damage. then all of a sudden they are at full health and go about attacking me.(This may be due to them taking a stimpack but usually they just stand there and I would notice then jabbing themselves with it) any one else have any of these issues?

I've just discovered the 'wacky gun' problem - didn't happen till I went to Nipton and entered the town hall. Now it seems to be popping up even in saved games before that. Very frustrating!
