When they posted, it was with the new changes in effect, not the old format.
The change in the date format is older than you think.
Edit : The new format was introduced around January, their posts was mid-march so I don't have reading problem thank you.
And again I played with the changes in effect and the usual strats still works.
Edit2: on my last save I only have 2 fighters (mc included), mc is slime and a lamia. Got Daisy for fishing and 4 prostitutes for a long time, got some more later to attain 10/10 and I cleared the requirements for the elections without problems. Learn to adapt your playstyle.
