Can the use of mob eggs be released? I'm trying to make a prison and I can't, as your not aloud to place villager eggs!
Mobs can create lag in large numbers, which some people would spawn as many as they could. There is also clear lag every so often so you would need to replace the mob every time clear lag hits.
Creative is extremely laggy, as so many plots have been made. Adding mob eggs could potential cause the creative server to crash, as many people like to spawn villagers and say "Wonder what happens if I keep doing this!".
