A nice fix would be to fix space assembling science because it requires red, green blue and optimization cards, but optimization cards can only be put into singularity lab from krastorio. nut the lab does not allow to put red, green and blue there. so its a deadlock...

That is actually correct. This research is meant to be done in the Space Science Lab in actual space. I probably should rather look into disabling the advanced and the singularity lab.

New update of your mod is crashing krastorio 2. Recipe of singularity beacon is problematic.

Should be fixed now. Forgot adding a check for SE 0.3
