The Ender Eye cant be Thrown in Flat Worlds..
Im Not sure if this Is a Bug or Just A Removed Feature, i Mean there are no Strongholds in a Flat world so i cant really Blame..
But if it is a Feature Remove, Please bring it Back, its Kind of Helpful with Commands (im Making a Horror Game, Sooo)
But if it is a BUG, May i Please beg you to Fix this? I relly need that Feature back...
Tysm
This is normal behavior since there is no stronghold to point to.
Same thing happens in previous versions of flat worlds
Note: If you have a normally generated world and destroy the end gateway blocks in creative, the Eyes of End will still point to that area, even though the portal was removed.
