I don't know if I'm the only one this is happening to, but I've recently been experiencing issues with the dragon debug rule in the A Game of Thrones mod. I remember playing games where there are up to 400 dragons in the world, but for some reason in my recent games the dragons are being eliminated despite the unlimited pseudo rule being active, and after the number of dragons in the world exceeds just 25, they are eliminated. I don't know if it's maybe one of the 65 submods I'm using, but it's annoying that this is happening and they are dying for no good reason.
