some quirks that need ironing out.
Tumbleweeds in certain locations ( Like Novac) don't blow around as they should and instead are stuck in one spot and can't
be moved even by running into them. It's like hitting a lightpole.
The lights from the Lucky 38 tower don't always illuminate at night when you at a very far distance, such as looking toward the strip from the goodsprings graveyard.
Exiting the game and reloading the save can fix this, and in that case it's a bug.
Surplus ammo doesn't seem to be recognized as an ammo type until you drop it on the ground and pick it back up.
Samual Kerr at 188 Trading post doesn't speak any dialogue when you click goodbye. He stands there for several seconds before returning you to normal gameplay.
