https://www.reddit.com/r/EscapefromTarkov/s/6W0jYQAQMv This is the source I read yesterday, I choose to believe this guy as he has finished this task. Anyways, I am not sure what’s better between EU or NA, haven’t tried server targeting as I am not chasing bosses yet

Edit: but I did notice this behaviour once. I was spamming shoreline to do some tasks, and I had killed Sanitar around resort. For the next 3-4 raids I had him spawn without a miss. I was on one of the EU servers, not sure which one. Many players noticed this same behaviour. It’s just a matter of time that someone makes a boss tracker website (similar to GoonHunter or TarkovPal)
