So I've been modding my HOI4 game, and tried modifying the trees.bmp file. The size of the trees.bmp file in my mod is 1650x600 and the province.bmp one is 5632x2048. I edited it using GIMP and saved it inside my mod folder. But for some reason the trees won't show up in the nudger in debug mode. It's just plain terrain, without any trees whatsoever. Any ideas? Thanks in advance.
