So I discovered a little something, and it doesn't seem like anyone else is really talking about it...

On the mission Legless Spider, me and a friend were looking for meteorites. He ended up going afk and just crouched in the boat. While I'm looking around, tons and tons of zombie drops start piling up near a few spots. It made my game lag at one point, and one of them was so big that it ended up refilling itself while I was collecting everything.

The rock next to the boat, the rocks near the car wreck, and the rocks near the little hole with water in it were the specific areas.

My only guess as to how it happens is that because the game spawns zombies constantly in this area, it had a glitch and just started dropping in loot until it hit some sort of limit instead of the actual zombies. I also noticed other collectibles like herbs and fluorescent shoots would also respawn quickly.

Any thoughts? It may be difficult for me to provide details since I've since moved past the mission, but I'll do my best to answer.

Do tell me if this is old and I just didn't look for it enough.
