Hello,
I make a new world in 1.8.1. I used this tool to see slime chunck :
http://chunkbase.com/apps/slime-finder#3038681710992808598
I find one and started to make a farm but no slime pop. My farm is in a chunck slime at y = 37 so i don't understand why they don't spawn.
More since the start I see no slime in my world.
I tryied to change my render distance to 12 etc... but that make no impact.
Thanks.
