Hotfix [8/25/2019]

Outpost attacks had some bugs, the main one being that not enough zombies were spawned in games with more than 4 players. I will of course be working to fix these problems ASAP, but in the mean time I have made the following temporary changes to try and make the next OA work a bit better:

- Games are now limited to 4 people per instance
- Zombies can now spawn a lot closer to players during an OA
