Hi, I'm trying to code a SEA overhaul mod, but I'm stuck on giving icons to a new estate I'm planning to add. The documentation on the wiki is surprisingly lackluster given that EU4 has one of the most well-documented modding wikis I've ever seen.

I'm not sure what or how exactly to define the icon. What I've done is copy the base image (estates_icons.dds) over to my mods' gfx/interface folder. Using photoshop, I discerned that the base image had a width of 264 pixels, which I divided by 6 to get 44 which I assumed was the width in pixels I needed to add to the base image before adding my own icon, so I did. I saved the image and wrote '7' on for icon code for my new estate. Everything else such as localisation and estate modifiers are showing up perfectly ingame, but I'm still missing the icon. I'm at a loss for what to do now, so any help would be greatly appreciated.

For reference, here is the new modified estates_icons.dds I made.

Thanks in advance!
