This happened before the most recent update as well. Every time I try to input commands in Mineplex, the game freezes and crashes. When the game crashes twice, it keeps kicking me to home screen then tells me to "Give It Another Try". I do as it says but to no avail. So I thought I would never play Minecraft again until a new update came out and it let me play again. But unfortunately it's impossible to play Mineplex games without putting in commands. So I thought the new fixes would have prevented it, but no, i'm stuck here again unable to play.
