It’s not working and it’s meant to be that way.
Those of you playing Marvel’s Avengers may have noticed that your ability to refresh weekly challenges has stopped working since the last update patch hit. The good news is that the team at Crystal Dynamics is aware of this. The bad news is that it is by design and won’t be re-enabled until it underlying issue is fixed.
Weekly mission refreshes have been disabled due to a bug resulting in a crash. At the very least you should be properly seeing both weeklies renew at the intended time and should be getting both weeklies instead of them randomly disappearing. Unfortunately you’ll have to deal with not being able to refresh broken/problematic weeklies until the next update hits.
Addressed an issue where refreshing a missing weekly mission would result in a crash. Weekly missions should now appear as intended. We’ve temporarily disabled refreshing incomplete challenges; full functionality will be restored in the next update.
