I participated and got the personal reward for the last event (July 2-9, don't remember the name of it though), but I did do back when it started and thus it was nowhere near the community goal, but now I see it's switched to the new one and I never redeemed the community reward for the last event. Does that mean I'm too late to get it now? That would kind of suck but it looked like it was really just a shirt, some experience (which is useless end-game maxed out) and some silver bars (which I wanted the most).
Well, I checked my game, but I don't even remember what the T-shirt reward is supposed to be for this past event. If I recall correctly it was using either Cheeseburger or Peaches to kill animals, so I used both to get through it faster, and I finished it the same day it started (July 2). I'm also playing on PS4, and in the past, I've also redeemed the Community Rewards for the ones I've participated in, as I've honestly missed a few at the very beginning. I am just hoping to get the Community Reward since I participated and completed my Personal Goal.
The problem is, once the next event goes live and you go to the event screen to accept the new event, it bypasses giving you the previous rewards. (It didn’t used to do that.) However, you can contact customer support and they should be able to help you.
I have run into this problem 3 times in the past, this now being the 4th. What they expect are screenshots showing you have completed the past event as proof, which you obviously can’t do once the past event is over. If it’s too late to provide that, try taking screenshots showing proof you have the personal reward in the shop menu and in-game - that’s what I did in the past and they’d eventually attach the rewards to my account.
I am now always taking screenshots of the event progression screen (showing I’ve completed it) and in-game/store menu screenshots as proof before the next event goes live, just in case.
Well, I just found something out simply by exploring. There appears to still be a way to redeem rewards because I just managed to get the first prize for the last event (since the community never hit the total goal for the second prize) so at least I got the silver bars I was really after anyway. What I did was I went to https://club.ubisoft.com/en-US/dashboard (basically the main page for Ubisoft Club at least for the US players), and right on that page it showed the last event with a link to click to "Redeem Prize 1" or something like that (I already don't remember the exact words cause my memory is really bad). So since that worked for me maybe it'll work for others, worth a shot since I stumbled across that.
