I'm not sure where to really put this, but I'm subbed to the Patreon, so I can access Backer builds, but I'm no longer receiving updates in my inbox when a new update goes live on Patreon.
I'm still getting notifications so I don't think there's anything preventing them from being sent out. Check your spam settings in case they've fallen in there somehow?
Then unless you accidentally disabled all notifications or Savin-specific ones, I've got nothing. I'm still getting notification of the updates including the most recent backers patch from a couple days ago so they're definitely still being sent.
