September rewards: Fix incoming (Patreon)

Hi!

Many of you received the message with the past sets to pick.

Many of you seem to not have received it for a reason that's beyond me (it was sent a longtime ago already)

Please note as well that September had no new rewards, only picking past sets and the trio rainbow content on tier 125!

We are working on the issue as I write this post.

Thank you for your patience!
