Hey ThundR,
Are you still planning on bringing this to FS25? If not would you be willing to let me pick apart the mod to make a standalone fillType increase mod?
One of my mods has been having severe issues when players try to use it with over 255 fillTypes so having this availible would be much better than just telling them to delete some productions 😁.
You can message me on Discord if you would rather talk one-on-one (Bbdude on discord, I'm in a handful of popular FS servers).
