Rockstar wants me to quit playing and buy another game

A few days ago, I "finished" Red Dead Redemption. I got to the ending but still had to help a few strangers, collect some plants, play some poker, etc. One of the things I still needed to do was get some beavers for the Daedalus dude. Those suckers were hard to find, but, thanks to the guidance provided on internet message boards, I discovered some near the river to the north of Beecher's Hope.

I was pretty excited because I had spent maybe two hours already looking for them and had ended up wandering around in the snowy parts of Tall Trees. It was there that I stumbled upon some sort of super spawning area. Initially, I saw some wolves near the path in the distance so I shot them to prevent an attack. As I was shooting them, however, more wolves were spawning in the trees nearby so there was literally an endless number of them. I rode past and got to a cabin near a river where I thought I'd look for some beavers. Unfortunately, the wolves kept spawning and attacking me and my horse, no matter how many I killed. I ran into the cabin but ended up being killed when a wolf leapt through the open door.

So, whatevs. There's a lot of wolves up there. Later, however, when I found the beavers, there was a rapid and endless spawning of cougars nearby and I ended up being killed and losing all the pelts I had collected. I was pretty livid.

Has the game gotten harder since its official end or am I just somehow stumbling across more rediculously active spawning areas? I don't remember any place where animals spawned so quickly before I "finished" the game. Now that I'm going around tying up loose ends, it seems like every time my horse is going too slowly or I'm on the ground for more than a few seconds in the wilderness, something attacks. And if I'm quick enough to kill it, three more animals spawn in its place.

Yesterday, I was trying to save someone from a wolf attack when a bear attacked me. Really, how many animals are in this game? At this rate, they'll be overrunning the towns in a week. Because I'm constantly paranoid about being attacked and can't get much done before being killed by a pack of twenty cougars, the game really isn't much fun to play anymore. Is this Rockstar's way of getting me to give up and buy another game?
