It seems the latest version, 0.69.44, is giving a "Technology rubia-long-stack-inserter: there is no lab that will accept all of the science packs this technology requires." error.

I have 20+ mods installed, so I am going to have to go through a lot of various mods to see what has changed when updating them. I have "Enable Planet Mods Lite", so there is going to be a lot to sift through to find which mod is conflicting.

I can revert to 0.69.43 and I no longer receive the error.

I would need to know which mod is messing with the labs.

I can almost guarantee that it is one that deletes biolabs, but the newer versions of Rubia should be immune to that.

EDIT: Update your mod. Rubia is on 0.69.48
A similar issue to what you are having was already fixed in 0.69.45

0.69.43 is the latest I can enable the mod due to 0.69.45 marking K2SO as incompatible and 0.69.44 giving the long inserter science error.

So, it sounds like 0.69.45 fixes the error I am seeing and marked K2SO as incompatible. 0.69.44 gives me the error with some mod in my list. So, that means I just have to leave it at 0.69.43 until K2SO issue is sorted out with.

Uh, K2SO didn't just start becoming incompatible with Rubia starting 0.69.45. I marked it as such because people were getting softlocked on Rubia because K2SO changed critical recipes and made it impossible to beat the planet. Work is underway to give it compatibility.

For now, I'm locking the thread as a duplicate of Krastorio 2 Spaced Out incompatibility.
