If you do use my shit I'd appreciate a shout out but hey I can''t stop you if you don't so you do you.
Bug fixes are absolutely allowed and encouraged, if you do make them please feel free to let me know so I can link the mod in the original mod page. As long as you're doing your own thing with the models/textures/script work and your own mod doesn't look the exact same as mine minus a few changes here and there we're all good. I don't mind anyone taking textures, meshes, or script function ideas from any of my mods, as long as you don't just copy paste everything and present it as your own.
