Does cryo STILL bugged and hordes of dogs assault you?
I don't know when you last played but at the moment Cryo isn't bugged. There are still many dogs there though. Cryo is in the middle of the dog spawning areas, so if you stay in Cryo long, there will be many dogs around. If you leave from Cryo in the first few days, you will meet very few dogs in the rest of the map.
I killed all dogs at radius 50 tiles away from cryo... But, as i think, cryo bugged and fucked me with five dogmans at night.
And yeah, there is spawn place of dogman?
Dogmen are more common in the north of the map, but you may find them anywhere. If 5 attacked you in the same day, maybe you were just very unlucky. Just remember that there are some things that make you a target, like making a lot of noise when scavenging, lighting torches and fires, staying in a specific area very long (leaving tracks and your scent all over the place) etc. If you do these things a lot, you will attract a lot of unwanted attention from wildlife and NPCs. Being more careful generally means less enemies will be coming after you.
