im getting a message saying the mod is incompatible with space age.
im using version 2.0.72, how is this possible?

The mod supports Quality and rail bridges if you have bought the DLC. But no space age. You have to disable that. – Kind of against the scenario of escaping a vast ocean planet.
I will eventually make it technically compatible with space age so that you can start the game with the mod. But the wohle Idea about space age is that you have different ores on different planets while the idea of this mod is that you do NOT have ores.

maybe you can make the other planets into oceans too? vulcanus is only lava, or fulgora that is all oil, etc

This is mostly a joke

Not joking that was the original idea. The code is still written in a way to include multiple planets. But since the game is intended to be playable without going to other planets. It would be only a gimmick and when I run into the first few problems, I shifted priority to other things.
But since there are multible space-age and SE variants of angles it is kind of is still in my head that you could do that.
