Chapter 4 proofing underway
By now, the proofers have had their hands on the BETA1 version of Chapter 4 for a day or so, and anyone who's eligible for the beta should have received a message about it.
If you think you should have gotten a message, but haven't, reach out to me and we'll sort it out.
And that also means things are looking good for a patron release somewhere in the second half of next week.
