Not showing threat/aggro from neutral mobs
Due to the UnitIsEnemy(tUnit, tTarget) condition in VUHDO_updateAllAggro(), neutral mobs are not taken into account when updating threat/aggro variables.
This is can be easily fixed by using not UnitIsFriend(tUnit, tTarget) instead, which I've only tried in WoW Classic with success.
