Still having this issue and reloading the world does not work. I watched Nick Stories videos and notice that, when he is using a structure block, the trail spawner reverted to Zomibies in place of the Glow Squid or Cow he placed in. Nick Story, did you place the spawner as a zombie before the structure block? I am trying to see if there is a way to have the sturcture block remeber the mob placed so that I can use the trail spawners as intended until this is fixed. Thanks for the help!

Still having this issue. In a realm where the gameode is set to survial, I have one account on survial and a second one in creative. Using the creative account, I place a new spawner and then place the mob egg in, then log the creative account out of the realm. Then, I battle with my survial account kill all the mobs and when the 30 minute cooldown is over, the spawner losses the mob and reverts to an empty one.

I am able to come back with the creative account and replace the mob egg, but the spawner will still lose the mob after the fight. 

I hope this gets fixed soon becuase the potential for creating maps is limitless if they get this fixed.
