Had to disband 4 quests (that possibly lead to more quests) in Glenumbra
Glenumbra has a number of quests and other misc. interactables that are fine for several hours after the server first comes up. But for whatever reason after an extended period of time those things begin to bug out and become less and less interactive as time slips by.
My advice is to go straight to those quests when the server comes up and complete them while you can... until the next time the server goes down.
