I noticed on Thursday or Friday of last week my feed has disappeared, assumed it was due to the issues the site was having at the time. it still doesn't exist. my mom plays too and she has her feed still available. unsure if it's a me thing or not.

This happened to me too. I think it cleared the cache. As my friends did more stuff on the site it started updating again. They may not have all actions triggered to show up in the feed. You can check here https://subeta.net/feed.php at the top there's "filter options" and "output options" you can check to see what actions are triggered and what's not
