Blast from the Past Event Missing Rewards

I completed weeks 1-3 of the Blast from the Past event but couldn't complete it due to one of the last week's tasks bugging out and refusing to complete no matter how many times I did it. I eventually just tried to claim the reward for the weeks I did complete, but could only claim the rewards for the first week. I really wanted the aspiration and banquet table! Preferably I'd be able to get all the rewards since I was prevented from doing so in time, but I really want those two from week three, especially since I did literally earn them.
