How does using modded .xml files in here work? I don't like making data backups and restoring them endlessly, but there isn't any info posted on where .xml mods go specifically. Do you activate them all with the "Use Mods" checkbox, or can you choose to use only a TechTree.xml mod? Can you have multiple mods of one file and choose which to use at run-time? If anyone knows, I'd love to see it in the modding wiki.
