I was saving 100 investiture to create fabrial but noticed I now have only 2 investiture, where I previously had 82 last I checked. Is there any reason I would have lost so much without noticing? I wasnt sieged or raided. At least my own lands werent, other vassals in the same realm have been. I've won a couple wars, thats the only notable thing thats happened to me since I saw this.

My monthly gain has stayed at +0.2 for a while now so not sure what it could be...
