My pokemon is holding a Life Orb (other methods will work, but this one is relatively easy). I defeat one of the enemy trainer's pokemon with an attack, and the life orb causes me to faint. We BOTH have pokemon remaining; the battle softlocks on a "Waiting..." prompt rather than let me select a new pokemon. I have to quit minecraft entirely since I have no method of ending the battle (no commands) and no method of disconnecting from the server (can't open the Esc menu).

Hey there! Interestingly enough, this doesn't seem to happen to me when I battle. Can you please send further evidence of this and if you have any other mods installed, list them as well?
