1 CMT1 is commonly caused by a duplication of a gene on chromosome 17. This gene controls the production of your nervesâ protective myelin sheath. CMT1 is also caused by other gene defects.  CMT2 results from a defect in your peripheral nerve cellsâ axon. This is caused by a defect in your mitofusin 2 gene.
Nakk the Thunderer was up twice within 10 MINUTES! He was up at 09:38 AM server time and again at ~09:48 AM. The first time I saw him and made a raid then we killed him (obviously it was on my server since I was the raid leader).our spawns between a 6 hour time frame then no spawns of either rare until 17 hours later jumps out at me as a little odd. I've since submitted a ticket to see if this is the case and to be honest I hope it gets fixed.
Hostile mobs have a spawning cycle once every game tick (1/20th of a second). Friendly and water mobs have only one spawning cycle every 400 ticks (20 seconds). Because of this, where conditions permit spawning, hostile mobs spawn frequently, but passive mobs (ie: animals) spawn very rarely.
