Nope, used fresh start, new mod installed, day 8 I get again 1.GM1 when S key, it saves only from 1 to 7, so day of the week only.
Autosave works but there is only one available, each turn - the game original autosave. The mod doesn't create each day-of-the-game autosave as it did before.
I disabled all mods except wog scripts and Era erm framework for the test. Using HD 5.4.R32, option save every day for tournaments disabled. I also tried without HD, same result
Edit: I tried on Tew 3, which uses a dat file, and it works, I get every day autosave. So only Alexander has the problem, no idea why. Does the mod require some wog script?
I checked month 4/1/1 and this:
gives 1, red, 1. The save shows only 1.gm1
