All the weather is copied directly from the original Orlunda planet. You may want to report any issues on that page. Unless this one is out of date.

Weather on this planet is sideways (rain going horizontally with weird vertical clouds, wind blowing from sky to surface. Not sure if thats this planet problem, or some incompatibility with other mods (I have none affecting weather)

Updated!

I take it you'll update this world again when Major Jon updates his?

the new respawn rover only lets you spawn on planets with an atmosphere of atleast 0.9 atm (this one is 0.89), because for some reason, the rover spawns a kilometer up in the air and needs a parachute to not crash. What a weird idea from Keen, just spawn it on the ground smh
Anyways, I'm fixing it, along with a lot of other planet related stuff that this update broke.
