Used to list our rewards, and gave the error.
Now it doesn’t list any rewards, and still gives error:
Noticed the Twitch Drop activated portion keeps requiring me to click activate.
Which is weird since it’s already activated, each time.
I would have loved the fox pet 
Hello @Keyrann;
I’m really sorry for this issue that you are having.
In this case you can follow some troubleshooting steps to see if it works.
1- Un-link Amazon, Twitch and Steam accounts and wait some time.
2- Link all accounts again and try to claim the drops.
Also, please check if you can see the drops in your Twitch inventory…
If non of this work please contact AGS Costumer Service so that they can help you escalate this to the devs.
Thanks for the report. 
Apparently related to Aldebaran server having its marketplace bugged.
