Saw that it wasn't mentioned here, but I'm having the same issue people on the steam page have where resources don't have a means of being improved. I'm gonna see if I can figure out why that's not working on my own but it's likely I won't know that easily. Thanks for doing this mod btw, was always confused why I couldn't find the original one for these resources, and the I saw it got removed. Edit: Nvm I might be stupid, I'm looking through the SQL file and see that platinum is assigned to masonry as the tech that allows it to be improved. TechCityTrade = 'TECH_MASONRY' as follows But that obviously shouldn't be correct. Also just gonna make sure it can actually be improved once i switch it to mining. Edit 2: Still couldn't be improved, I have no idea then. Hopefully I can try and spot something that seems like the correct thing, a boolean maybe with my lackluster knowledge of programming.
