Hi there; someone reported this https://github.com/nicholasgower/planet-muluna/issues/180 and I jumped on it and asked a bit.

Point is, with Cupric Asteroids default settings, the metallic byproduct is changed from copper to uranium ore. I've seen that you had thoughts about it when looking at the changelog.

Now, Muluna is pretty special, since it introduces mining patches on the planet surface containing asteroids. They don't have a cupric mining patch. Thus, you cannot get copper ore on Muluna. It's not a show stopper, you can always import plates, but Muluna intends to provide copper ore via the metallic asteroids.

When I change the byproduct in the settings for the metallic asteroids, everything's back to "normal". I think I'll do this in my save and honor the cupric asteroids nonetheless, even though that's probably not what you intended, I guess it diminishes the need for mining the cupric asteroids (I haven't looked at ratios or anything beyond).

What do you think? Maybe Muluna's author and you would have to talk about that...

For me, it's fine, I'll run with the copper ore byproduct. So no bug here, and not really an incompatibility, more a clash of each mod's author's intentions I believe...
