...also i have yet to be raided and i have killed 40+ and kidnappedd 40+ is this a bug
Probably not. With enough secrecy on your safehouse, you can sustain significantly larger body counts than that before getting raided, assuming you aren't just chilling there. The game isn't designed to be realistic in this; it's designed to be fun, which means you don't get raided real quick.
There should also be some sort of encumbrance/capacity thing, and maybe backpacks and such to deal with that. It just seemed unrealistic when poor Rex, almost crushed to death by the weight of thousands of suits, still managed to crawl his way, I imagine screaming in agony and sobbing at the cruelty of the Liberal Crime Squad, to the pawn shop.
If it's just a matter of just going to the pawnshop with what's in the safehouse, it's assumed you can abstract any number of trips/carts/whatever. If you really have thousands of suits, that's pretty wild and unusual. I don't think it'd benefit the game much to force you to do the same pawnshop trip several days in a row in order to sell all your loot.
It used to be that you could bring tons of guns and weapons with you on site. The problem was that there it did feel odd that you had a whole armory in your back pocket, and it allowed you to avoid stealth restrictions. You could suit up in heavy body armor and assault rifles after penetrating deep into the place and right before you set off the alarm. That's pretty weird. I wouldn't have an issue with a bag system (several options for having bags were proposed back when squad inventory was still in place), but it'd be a fair amount of coding to get a decent one in place, so it has to contend with other priorities.
