I had completed the first two step in the warplan then went on vacation for almost two weeks. Since I came back the next activity in the plan is two back to back helltides. I have done at least 5 helltides and opened probably over 20 of the chest and no progress. So of course I am locked out of completing any warplans and I cannot re-reoll the plan. For the love of god fix this issue.
EDIT: ok, I think I figured out my issues. I happened to notice when looking at the Quest log in the world map, I had a priority quest for an Infernal Horde, so I used one of my keys and knocked that quest out. Then the next priority quest that showed up was my…wait for it… Helltide Harvest. So I was finally able to complete it AND get credit for it. So I guess the Priority quests - if any - must be completed first IF it is different than the “current” active warplan
