I've made it step 3 of the Wish Ender quest, cleansed the mementos, and am unable to present them to Sjur Eido. I've attempted it three times and no one in the three different Fireteams has been able to present the mementos after the final boss. All of us are seeing the same "Cleansed mementos required ..." message. Is there a work around or fix for this bug?
