i'm getting fed up of buying supplies twice due to the game crashing, it only happens in populated lobbies...
my supplies had run out so i bought supplies for $75k, then chose to sell my stock and the game crashed as i hit 'confim',
i tried glitching out to a solo public but it didnt help, had to restart the game, then my suppies didnt arrive so i had to re-order them costing another $75k
i know it took the money the first time as i made a note of how much i had before buying them,
so not only do you have the gamble whether to sell in a populated lobby for a bit of extra cash,
there's also the gamble of whether the game will crash as you try to launch the sell mission :/
