I tried this today with rum, I have yet to try it with beer but I assume it's the same thing. But when I got like 8 mugs and filled them all with rum from the same barrel at the same time, they all had different damage values. The different damage values means I can't sell them in Trade-O-Mats, I tried and it didn't work. Does anyone have a solution to this problem? I really want to sell rum and beer at my bar.
