Not sure if this is really a bug or not, but the other day I was hunting in the Great Plains and saw three or four pronghorns. I immediately started galloping towards them with my gun aimed, and only two of them took off. One of them just stood there. I literally got off my horse and stood right beside it and it didn't even move LOL it just stood there like it was staring into space. So like any good cowboy, I took out my melee knife and took advantage of the situation and sliced it. Actually I think I have a video of it I may post it later, I thought it was pretty weird and funny at the same time!
