Why are my war table operations showing 100k hours remaining

I returned to one of my Inquisition playthroughs after about two months. I've taken breaks from playing before and everything was fine, it just took a minute to sort out what my character had been doing. But this time. It loaded directly in front of the war room so I go inside. All three advisors were working on operations - "Ser Barris Leads Against Demons," "The Serpent of Nevarra," and "Exalted Plains Resources." All three show over 100k hours until completion. Why....? This has happened before on a previous, deleted play through (a dwarf rather than a qunari, but both are rogues) but never more than 10 hours before now.
