Some basics I have learned the last 24 hours. - Hotloading is now supported. Often 2 saves of the file are required for Civ6 to correctly load the changes. - If you add new files to your .modinfo, you unfortunately need to reboot the entire game for them to get loaded. (Maybe if you change the mods uuid you dont?) - Still no idea how to load a custom .lua file via .modinfo. But loading files that are located in Base/Assets works fine, and the new files override the old (currently only DLC case was tested). Adding a custom.lua file that is not included makes the game not want to load it.
