I was trying to put down a cow spawn egg that i got from a challenge completion, but i couldn't so when i asked someone told me that they could only be places down at 7am EST which I am never able to be on at that time. I was wondering if the time could be changed or just removed somehow. Because I need the cow eggs to complete another challenge.

 

Needs fixing ASAP, also you sometimes get the wrong spawn egg when completing a challenge.

 

No you can't use spawn eggs at all unless it's for a spawner, and you can only do that at 4 am EST after the server restarts
