Wasn't that issue solved when SPELL_GROUP_STACK_RULE_EXCLUSIVE_SAME_EFFECT was implemented?
I remember that now in GetTotalAuraMultiplierByMiscMask() only the aura with highest value is applied among a group with that stack rule. So it should include even auras with same spell id.
Probably now only Crypt Fever is still bugged, can someone test it?
