I'm playing with gigstructural engineering and more. Megastructure remover doesn't recognize "fusion fuel depot". As the "fusion fuel depot" is an upgrade from "Asteroid industrial site". I tested whether the mod works with a dysonsphere and it gives me the prompt to remove it, but it does not give a prompt for fusion fuel depot. I hypothesize it doesn't recognize other structures that upgrade/change either. Let me know if you need additional information or screenshots.
