My current progress/some things I'm having trouble with

I also made it easy to get a lot of metals and xp for testing purposes (I may remove before I release the mod)

I've ran into two problems with what I'm currently trying to do, I decided to handle hex more after I get some of the basic stuff I'm having trouble with which are

Adding new Schools

Adding new Ranks

Some of the general pictures not working

Adding countries (I mostly know how to but it always crashes the game when I go to conquests)

for the schools I know how I should but I think I'm missing something (I updated the stringtables and made the new one in the schools.json but I'm pretty sure I'm missing one thing since everytime I try to add one it removes them all)

Ranks is the same way exept for when I try to add a new one it just crashes the game

Oddly enough I have no idea why but sometimes my general pictures won't work and it's not that I got the coords on the small heads wrong or made the image wrong I've triple checks the coords and made sure it was the right image and the head images only work in some places like if you click or tap on Hindenburg you'll see his works but if you just see it regularly even though it's the same image it won't work.

I know mostly how to add countries I was just trying to have them in the files at the time since I'm just begining to learn hex but it keeps crashing when I go to conquests.

Is there any way I can fix these and is there anything I'm missing all help is appreciated

Thanks! It's not much right now but now that I've began to learn hex I'll be doing much more.
