I used bioval once because I ran out of bastards and another player game them to me. It was a super rainy day, actually it's been raining for a few days, it was so humid it eventually became foggy. The Biovals stopped feeding in almost all my mags, they just gobbled the humidity and increased in size.
I've been playing for years with Bastards bio and Madbull PLA bio now and that never ever happened. They always fed perfectly in all my mags, no matter what the weather threw at them. Hell, I even had bastards bio half submerged in water for a week when they were new and wanted to test them and they fed perfectly, although accuracy was of course reduced.
