Whenever a player with some gear enters your network bubble, the game freezes for a tiny bit. Looks like the devs cannot fix this since a few months.
Funny thing is: I had several hard freezes within a few meters of running, my game almost got stuck and i almost got killed by zombies. So i guessed, its either a big group of players OR a lot of containers/barrels,...
I got interested. Well, i tried to run back, reconnected and tried another approach until it froze again.
So long story short:
I found a nice base with Barrels and stuff just by getting the right direction of freezes and getting aware that i should look a bit better.
The good thing, as base strength levels are still completely broken, i easily broke 1 lower part of the fence with my sledgehammer in 1 minute and got all the sweet loot.
Later i thought i take the base over, so i just bruteforced the 3digit codelock within 15min.
Problem was that only a few minutes later 1 guy jumped on his friend and then over the fence inside my new base and killed me :(
So it looks like the freezes dont just tell you when to expect some player encounter, but also that you are not too far away from bases.
I am not alone with that:
