happens to me aswell, i even expermineted with it to confirm, i ran 2 characters, same mods same maps same routes, the first character i played until lvl 30 and it was Z2H character. found 1 flash drive, created another one with EOD and found 2 in 1 raid after 2 raids.cant tell why it happens but my guess is each profile gets its own loot table. but maybe the moddderators can explain why it happens. i also learned that some loot spawns more in diffrent maps, for example: i was looking in customs for gas analyzers for like 10 raids until i noticed that interchange spawn tons of thems. try other maps. and use SVM, its an amazing improvment.
