I've noticed an occasional problem with throwing grenades that causes them to travel only a few feet. I have seen it happen a couple of times in the penthouse of the Lucky 38 when I am going after Mr. House and fighting his robots, trying to hit them with pulse grenades or regular grenades. I've also seen it in a few other places. I can't remember it ever happening outside so I think it only happens indoors. It happens using VATS as well. And my limbs AREN"T crippled. I check.
It's kind of like when a little kid says "Look what I can do!" and they throw a ball and it only goes a few feet in front of them and you are supposed to act amazed. (keep practicing kids, I'm not impressed) But my character is a grown man so what's going on?
If anyone else has had this occur I'd like to know. Also, If you have any other glitches to mention feel free to bring it up here. I had a glitch thread going a while back but it's buried way in the bottom, probably around page 10 or so, and I don't want to repost in it pointlessly just to ressurect it.
Yes, that has happened to me too, both on Fallout 3 and Fallout New Vegas. The first time it happened on Fallout 3, I actually had a similar reaction (did a baby take over this?).
If I recall right (I haven't played either game in a few months), you basically can't just tap the grenade button. You have to hold it down a little first before letting go.
