1. (Big) Casus Belli Mousetrap:
Spain got a Temporary CB vs Georgia, DOW was not an option (in fact there were no diplomatic actions available because it said it was a satellite of Russia). No ability to DOW Russia either, except maybe by forging a CB since they had already DOWd on France on some basis. Spain was docked 50ish VPs for not DOWing. I had assumed that chain DOWs would give Spain (at war with Britain from the start) CBs on others.
2. (Small) The message for National Will post-1.01 is "opt_notify_CMN_SUperiorNationalWillFMSPA"
That is for a start.
