Major/relevant mods I have: K2SO, Maraxis, Planetaris suite, Moshine, Space Platform Start, RSO, and Alien Biomes, all on v2.1 (latest experimental)

I built a ship capable of getting back from crucible, loaded it up with a factory, dropped it on Crucible, did a few of the first trigger techs, and then went off on a journey for some emulsion or skarn. A few minutes of walking in a spiral outwards in some speedy mech armour and I still haven't found anything, no emulsion, no skarn, no whatever else might be on this planet. All I can find are some pools of lava and these weird pink mud pit looking formations. Emulsion and skarn are touched by Resource Spawner Overhaul and Alien Biomes based in their info panels, so those are the two main culprits, though they aren't marked as incompatible and they're major mods that I'm sure others have used here before me so I'm not sure.

At this point I may be stuck here without using cheats, as without access to the resources I need to make the science, and thus the fuel, I can't get my character off-world to do a surface reset even if there is a fix. Hoping you got something for me.

Thanks for reporting, I'll take a look! If you send me your save file it'd help too.

Wasn't sure how else so I just put it on drive.

Thanks! I was able to use your save to test that the fix works.

The issue was RSO, and I've added compatibility to Crucible v1.2.5 so that the planet's resources generate normally. Unfortunately you'll still have to delete the surface for resources to start generating; but the game will just teleport you back to Nauvis, so you don't actually need to be able to leave the planet to delete the surface (/c game.delete_surface("crucible")).

Also, Crucible v1.2.5 requires the latest Factorio version, 2.1.22, which introduced some breaking API changes, so a bunch of mods had errors. I'm sure they'll all be updated pretty soon though.

That was the fastest turn-around time I've ever seen on a mod, thanks. Also I'm massively surprised it was RSO, I really thought that somebody would have used that on crucible before me, to my knowledge it's a fairly popular mod. I also didn't know I could reset a surface my character is on, I'd always seen the opposite online, so that helps.
