There's 2 different bugs about weapons, you confused them.
First bug: is about getting wrong weapons when I leaved the game and quickly rejoin. I bought that weapon list (which is what I buy usually, except parachute). Today I leaved normally 3 times and I forced it from Task Manager to get timeout another 2 times. My weapons got messed 3 of these times, I got pistols rather than Deagle, Combat Shotgun rather than Sawn-off Shotgun, Tec9 rather than MicroUzi. M4, Sniper Rifle, and Parachute remained.
Second bug is that if I buy MicroUzi / Tec9 / MP5 then I buy another of these IN SAME GAME SESSION, it will have no effect on future spawns. Every future spawn I got the weapon bought first.
Hmm... I think that I just found a third bug related to leaving and rejoin...
