[RESOLVED BY ALTERNATIVES] If you put 64 pieces of armor (All one type like leather cap, and all ONE stack) into a dispenser, then apply a redstone signal, only 1 piece of armor comes out and theres no more armor left in the dispenser.
Say you put 1 stack of leather caps in a dispenser (Pic 1) then you place a lever on the dispenser and turn the lever on (Pic 2). It seems the dispenser eats all the other 63 leather caps and shoots out 1 only (Pic 3). If you open the dispenser inventory again, you will see that there is no more armor in the dispenser (Pic 4)! This also happens when you put a stack of potions in a dispenser.(Pic 5, 6, 7, and 8) My guess is, this happens to items that are not supposed to stack. Please fix this!
