I've just hit Prestige 3 and went to the Prestige store to unlock more gear. I unlocked Bouncing Betties, as I've already unlocked my favourite weapons after previous prestiges. However, I got to level 4 of my next playthrough and two of the weapons I had unlocked - Type 95 and Stinger - were were now locked again. I'm pretty pissed off, as the other two - AK47 and P90 - are both still unlocked, and they're my least favourite! Has anyone else had a similar thing happen to them? Don't suppose there's a fix, is there?
