It would seem all or most of the spawning locations as of 1.26 experimental are from solnichniy to berezino. I have only had 3 spawns at cherno only 1 at sevt an 2 only at kamyshovo every other spawn is between solnichniy an berezino witch really sucks be that’s where most of all the geared 4 mans are with NVGs an suppressed weapons so every one just dies an a none stop repeat of the Exact same spawn locations
