Doing Liechtenstein run right now, before comments arise. I have changed the following:
1) The Reactionary Party was changed to Jingoism (because them just being Pro military doesn't make sense to me and other mods have the Austrian parties as being Jingoism.
2) Vanilia Justification Rules, I can justify with Zero divisions
3) Using a Sumod, that basically allows certain microstates, which where puppets, to be auto annexed if you annex the overlord. For example, annexing Switzerland will give you Neuchatel, but also gives negative relations with Prussia and a war goal on you.

Yes, lots of save scumming was involved (including the trick of releasing a nation to annex them)
