On westfall I cannot aggro some mobs.
Starting to fight, my first hit is decreased from their hit point. But then the mob reset the aggro.
And just after retry to aggro me, and immediatly reset.
Note that their "familiar" can be fight normally. Example the murloc hunter cannot be fight but its crab familiar can be killed.
Moving my character back to any other zone, permit it to fight normally.
on the mangosd log, I see "creature started to attack player xxx" then "creature stopped to attack player xxx"
This bug happen since february, and I have update to the latest github sources and still happen
