Actual Aporkalypse

I was in the Academy when the shopkeep got stuck pathing over to replace the relic i had just bought. Pushing him didn't work, so I smacked him with a halberd, causing two guards to spawn. I was frightened, so I just left the building, but noticed later that while in my house a bunch of pigs were spawning out of bounds. It happens on each interior map I've entered (including other shops, ruins, etc). I'm theorizing that I could stop their spawns by killing them all off, but I simply don't have the firepower. 

Sneaky, Klei. I've found your Aporkalypse before you even released it.
