Hello, The issue related to trials mementos not dropping should have been fixed in the recent [url=https://www.bungie.net/en/Explore/Detail/News/51206]4.0.0.5 hotfix[/url]. I haven't heard of the gambit memento being bugged as of now, so let me know if you are able to get it to drop at any point. [quote]Fixed an issue where Trials of Osiris Mementos were not dropping when players claimed their first Flawless chest of the week. [/quote]
