My friends and I started on a solar system map on mars, anywhere we went, we could not find a single bit of Pt. Is that the game's normal balance or this mod?

If you are referring to the vanilla system's red planet, it should have the custom ores injected by this mod.
If it is a custom solar system (i.e. a downloaded mod map), whether it has Pt or the ores from this mod depends strictly on what the authors of said map added.
As I can't make head or tails of how to code in this game because how out of date all the guides were when I attempted to research it, I currently have no way of coding in random or automated ore-rebalancing, either.

You already mentioned this in the comment section but id thought i would post it in here so someone knows the answer.
Platinum is not found in planets even with this mod installed (unless the author changes that in the future, though i don't know if i want him to for balance)
