Hey, so I don't know if this is the right place, but a friend an I were playing on a local host on his computer in version b221, and not more than... 30 minutes ago (at time of writing) and we were kinda messing around in creative and doing stupid stuff with timer relays and speakers, when suddenly 2 Zbears spawned, we killed them no issue, he stepped away to cook food, so I continued to mess with things, and suddenly had a screamer spawned and yelled. I killed her and looked around for her "hoard" to spawn, and it didn't. I thougth nothing of it and went back to setting up the timers, when I had a Feral zombie spawn on my head (more or less), killed it, went back to building and then suddenly I had about.. 20-25 Rad Ferals spawn, and then a handful of construction zombies, and then another 100 or so rad feral spawn again, I brought out a rocket launcher, began to shoot them, didn't do much. I turned to my friend and shot him, and killed him (we were party members and friends in game, bug?), but they kept spawning... we had no idea what was happening, it was only the two of us on the server, friends only, and all the zombies kept spawning in the exact same place, causing massive lag each time another batch spawned.
In the end we ended up killing them with a Super Dev Wrench and Digger, but not before they dug a massive hole in the ground. as we looked over the hole they dug, about 50 more spawned ON my friends head, after I'd dug up the spot where they'd spawned, so he force closed the server and as I went back to re-launch my game (memory leak, was getting a bit high), I noticed the update for 7dtd. I don't know if it was the games way of saying "Hey, update", or if a dev or someone hacked into the game and began to troll us... I just wanted to write this out so SOMEONE would see, and maybe if they've had it happen to them...
Also putting it here cus I think it was a bug with spawning or something....
