I have lit up my Villager farm on my own server and zombies are spawning like crazy.
I have checked every where for low lighting but their is no chance in hell they can spawn.

I got a snap shot with a mod called Xray cause of this problem i am losing all my Hard Work.
I change gamemode so i can kill the zombies but it is not fair ;(

I dont know if my building has anything that allows zombies to spawn or it is made so you need to have Golems to protect the Villagers.
But why are they spawning in lit up area with no dark spots what so ever.
THEIR IS NO WAY ZOMBIES SPAWN!
I did reinstatement the server and it hasn't worked.

Also this is Bukkit server updated with only Essentials mod installed.
A person i know with this does not Belive it to be a problem with the mods or the server but a bug in the game.
