Anyone see an issue..?

if i had to guess, i would say that you can't use quest::selfcast() in EVENT_TIMER because it should be looking for the client that initiated the event.

i'd suggest starting those timers only when the npc was engaged (as well as stopping them when it is disengaged instead of just dead) and then pulling the target for the spell from the npc's hate list, since there is no need for the timers to be running constantly.
