It may be on Xbox 1/360 and Ps4/3 however it is in fact on ps4.

while playing i trapped a mobspawner for zombies, it spawned things a few times then it stopped, converted to a pig spawner, then stopped spawning anything. after using a zombie spawn egg or ANY egg there after it would convert the mob icon inside, spawn one of that mob, then revert yet again to a pig and spawn nothing at all. i changed the gamemodes, difficulty to peaceful, normal etc back and forth and it wont fix. other mob spawner i had would spawn skeletons now its doing the same. its literally nearly broken as far as farms go...not worth playing if my farms are broken.
