David_Mozi submitted a new mod: Extended Ship Fuellimit - A Mod for increasing the max fuellevel for the higher tier ships. Read more about this mod...
I haven't looked at this mod's files, but I already know exactly what it's doing and how... because there's only one way. You'd need to upgrade you ship. No way around that. This is a value in the .structure files. Starbound only looks at them upon upgrading. The only option for fully upgraded characters on that front is a ship wipe, which I don't feel like explaining this very second. I'm due for bed. But if you are considering that, you might also consider if you want to stick with a vanilla ship or not. Some people of course prefer them, and some don't.
Yikes. Well, I'll see how I like it when I upgrade another character, and decide then. Thank you for explaining!
