I have been working for the past two days trying to make the squall a buildable unit for a test mod i'm making. However, to spite all of my efforts, i cannot get the drone to show up on the build bar. I have edited the build.js and the unit_list, but is there something i'm missing? Basically all i did to edit the build.js is replace the bot_fabricator with the drone so the drone would show up in the fab's spot. However, the drone refuses to. I know it has a UI icon and settings and things, but why would the drone not be displayed on the UI?
