This is what happened from my end.
I spawned in debug forest and ran to meet up with folks north of Zolengorsk - we checked out the green mountain military facility, i had to kill a lot of zombies for no loot (there's no enterable buildings in there and the tower which can be entered has 1-2 lots of civilian loot only).
Then I ran all the way to Prigorodki to meet up with Jarni and Yvnu.
North of progorodki we meet up. I get visual on Jarni but not on Yvnu but Jarni knows where everyone is and giving directions so i trust him.
Then Jarni spots player Dan running through the open fields and relays location. I get into position and begin firing getting a confirmed kill on Dan. We go to loot and get stuff (at this stage I still have not had a visual on Yvnu I think.
Then we go back to tree line when there are shots fired. We assume Dan has ran back! In the confusion I spot a player targeting Jarni! I resolve his tag long enough to see that it doesn't start with =TOG= so i open fire on what I assume is a hostile

I am really sorry Yvnu.
Too bad after that Dan 100% outplayed Jarni and I - I don't think he logged to another server,flanked us, logged back in. He actually properly outplayed us - he was in exactly opposite direction Jarni and I expected him to be meaning he walked right up to jarni and I and headshoted both of us with a pistol because we were too focused on looking in one direction.
Lesson there is to do strategic retreat even further I think. And never focus too much in one direction.
Later that nigth turned out to be a huge mess by the way

Electro is easily the worst area in the game. It is full of new or semi new players spawning at the beach, pistoling other newbies then running 20-50 zombies in a train formation towards other players. I am not sure if this is griefing or actually being new or what but it's cheap and unfun and i am emotional about it. I spent close to an hour worth of running/sneaking trying to get something out of electro and the best attempted ended at the church with a gun sprinting all the way from the beach right into me with a train of zombies that promptly killed me. Summary: electro has worse loot than cherno by far and the biggest amount of outright chaotic pistol gunfiring.
10min in cherno and i got 2 kobras, alice pack full of ammo+food, matches.
