- Had to abandon the incursion and now I don't have enough World quests to repeat it
- The incursion event ended before I could hand in my quest and it disappeared from my log, I'd like the equipment cache reward
When Battle for Azeroth Assault/Incursion events end, the quests for that event are automatically abandoned from your character's quest log.
If you abandoned the quest mid-progress you will have to start over when re-accepting it, just as you would with a normal quest. If there are not enough world quests available to complete the current assault, you will need to wait for the next one.
Game Masters cannot restore progress for expired or abandoned quests.
