I'm not really sure which ones to send you, so I'll send you all of the ones that seem relevant to my inquiry. The research I want are Fusion Explosives (Researches.FusionExplosives) and Marauder X-37 (Researches.MarauderInterceptor).
researches.xml - Xenonauts fix pack
researches.xml - Xenonauts default
researches.xml - Xenonauts Community Edition
researches.xml - Armored Assault
I have the Steam version but for some reason, it got messed up, as in, it keeps on telling me that my Community Edition is not properly set up when it comes to priority. Trying to manually make it the first priority just puts it at the end of the list again when I start the game.
And it'll keep on asking me to automatically put it in the right place, every time I start the game.
To be fair, I'm not sure what other research is messed up in my game files and I can't see what exactly is going on with these mods since I made sure they're identical with their changes (for the Marauder, I set the requirements to be able to research them as "Get alloys", it didn't work until I found out I didn't edit the right Researches.xml, but now I can't remember which one was that).
