For some reason it allows me to buy some potions but not others even though whats in the chest is the same as whats displayed as being sold? Same with food, I sell steak for 6 coins, and chicken for 4 but chicken can't be bought when steak can??? Also my friends on my server reported that they can buy things on machines that work, however all they see on the being sold side is diamonds regardless to whats really for sale?
There's also a bug where items in your inventory can duplicate once or twice then disappear when you try to use the duplicated item leaving the normal one behind, not sure if these are known bugs or not but i'm just a little confused
