How to reseach Oil processing on Tiberium only run? It needs to gather Crude oil. I can't make crude oil without molten tiberium that is locked behind Thermal Tiberium Testing reasech that need Oil processing and refineries.

Fixed in version 2.0.3

Tested on 2.0.5 I think the option "Tiberium initially spawn on" is reversed. Tested without space age. The option "Nauvis has only tiberium" in new game and on my save from 2.0.2 still has mine Crude Oil in technologgy. The option "Nauvis has Tiberium" the mine Crude Oil has been replaced with a normal research in both occasions. On new game available ores are correct, the Nauvis only option hides the other ores.

Thanks for the report, I can see that I fixed it in one commit of 2.0.3 and then broke it in a later one. Fixed for the next version

The option "Nauvis has Tiberium" the mine Crude Oil has been replaced with a normal research in both occasions.

I can't replicate this, can you share your mod list?

What I mean is that on "Nauvis has Tiberium" option instead of have "Mine Crude Oil" to research "Oil Processing" it has red and green science packs, that is the correct/fixed way to do a Tiberium only run. Isn't it?

In the "Nauvis has Tiberium" mode, oil production research is automatically investigated, but to create blue scientific packages, oil is still required, and it is not possible to extract it with the help of tiberium at this level of development, and there is no spawn resource, please fix this flaw, it does not make it possible

If you are playing on "Nauvis has Tiberium" mode, then crude oil still spawns on the map, Oil Processing still requires you to mine crude oil, and your blue science progression isn't gated by Tiberium.
If you are playing on "Nauvis has Only Tiberium" mode, then crude oil does not spawn on the map, Oil Processing requires red and green science, you should be able to get Crude Oil from the Molten Tiberium Separation recipe unlocked by the Molten Tiberium Centrifuging tech. If you do not have oil or other resources needed to progress to blue science from that recipe, please share your mod list so I can investigate.
I see what you are talking about with the Molten Tiberium->Crude Oil recipe moved to higher tech and I've fixed this for 2.0.7 but I'm still interested in what your Molten Tiberium Separation recipe looks like

When will the update be available?

As of 2.0.6 I can continue my save and research all oil tech on a "Nauvis has Only Tiberium" mode. I had to research some oil tech (with red/green science) before I got the recipe for tiberium -> crude oil, but it's totally playable now.
