Ok I decided to try the game again now that it's not so crowded anymore =p
Anyway...I got Ender's to work and I can show radius around animals and can make the curios show in the minimap and all that. But for some reason I can't hide anything, I know I used to be able to hide rocks, walls and trees and such but now I just can't remember if I have to do anything but just "hide trees" since that does nothing =/
