Currently, your mod replaces the uranium rounds with thorium recipes. This kind of breaks the game flow for the mod Castra, that has uranium rounds as an ingredient for the local science pack and relies on them being produced out of uranium, since that resource can be found on its surface. While this does not create a full incompatibility with the mod, it does feel weird to have to leave the planet unfinished, play through your whole mod, then import stuff from there to Castra, especially since Castra is kind of on a timer for tech from those science packs as far as i understood it without being able to unlock the tech yet. I hope I´m not making this post out of some misunderstanding on my end :)

Instead of declaring those mods as partially incompatible/not recommended together I do see the chance to just make a new ammo category in your mod that either exists alongside uranium rounds or has those as an ingredient instead of replacing them. Unless there is a specific reason you would rather change the recipes of the existing ammunitions?

Otherwise, thanks for making the mod. I do like it a lot so far, it has some really nice ideas implemented.

Update: disregard please. I noticed that some updates seems to have changed the recipes in a way that no longer break the Castra science (I think I was even wrong in the first place about your mod replacing the tech - sorry).
