Based on your debug stack [string "@Questie/Modules/Tracker/TrackerUtils.lua"]:760: in function func'`

This line in within the questProximityTimer where QuestieTracker:Update() is called. It's also wrapped in the CombatQueue so it wouldn't have fired an update while in combat.

I goofed with this on a new toon for several quests while using the Proximity sort feature. No issues...
