Steps:
1. After completing Alexander Savage 1 for this weeks clear I did not receive a
Gordian Manifesto - Page 1. Shortly after this, I completed Savage 2 with the same group and received my Gordian Manifesto - Page 2 but nothing for Alex 1. Some in the group had already cleared Savage 1 that week so no loot chests dropped but I still should have got my Book/Page 1.

Did you enter A2S at some point before clearing A1S this week? Entering A2S counts as you having cleared A1S already for the week.
