[1.0.4] Random Cultist event bugs if you one-shot a cultist

[DragonMasterHawk]

A few notes:

- Damaging a cultist's bone shield does not aggro their faction
- Mana clashing a cultist with bone shield up does not aggro their faction
- One-shotting a cultist once their bone shield is down does not aggro their faction

Beginning the timed event while the cultists are not aggro'd to you will put you in a very buggy situation. The timer will never move from 210, regardless of what you do. You may go and kill all the other cultists, and the event will never proceed, even if you aggro them normally. Zoning has no effect.
