RSO should work with Angel's ores but there are a lot of settings that can affect that.
Please check if any of ore generations is enabled in RSO (vanilla or RSO one).
I'd need a save to sync settings if you have different ones then default plus to sync mods since it can vary - can be through forums or link to some file transfer site here.
Hey, thanks for the quick response! I double-checked the settings for Angel's Refining and all of the Angel Ores were disabled in the starting area.
I have Seablock running on an alternate save and I think that disabled them, and they didn't get re-enabled when I tried to generate a new save. I'll just reset my mod settings. I really wish I'd caught that before I made this post lol
