Re: [Weekly projects exotic caches not received](/topic/131586/weekly-projects-exotic-caches-not-received)
Similar issue happened to me, like what is described in the topic linked above.
I play on PC, WIndows 11. As i had recently returned to game, i checked rewards, and since the simplest ways to get something nice are projects, i am sure there were three projects which would reward exotic cache (i am writing this, since in previous topic there is comment, that weekly project does not reward exotic cache, and i have no way of checking or proving what the rewards were as i have it completed that project now). The 3 projects were were 30 floors of Summit, bunch of donations and do activities, missions and emotes with players. I finished donations project easily and received exotic cache. After that i aimed to complete project which required activities with other players. Last objective i needed to complete for this project was to play mission with players. I did matchmaking from one of the safehouses, got matched into another players session and we completed the mission. I did not notice if i had project completion blings on interface. The session owner player left the session, however i went back remember where they would go). After that I found the thread linked above, and tried relogging, waiting 24 hours and clearing checkpoint, nothing helped, i still didn't get the cache.
