Hi,
There is a softlock on Rubia because of the tech card replacement of this mod. The Project Thrashdragon research's trigger is yeeting 1k of the Rubia tech cards with the Crapapult after changing the Rubia science to be tech card based by this mod. This is impossible to do because tech cards can only be made in Research Servers and crafting a Research Server requires Electric Components which are unavailable on Rubia and cargo drops are locked behind a tech after Project Thrashdragon.
I have a few different fix ideas (which I tried to use on my save with a custom mod):
1. Change the trigger for Project Thrashdragon to yeet 1k data cards instead of tech cards (likely the most theme-appropriate/best fix, but I tried and failed to implement this because the yeeting recipes and items were too hard for me to understand in the Rubia mod code)
2. Add a new, Rubia-compatible recipe to craft research servers, so they can be crafted locally without Electric Components (this is likely a good fix as Rubia itself has K2SO compatibility code which basically adds new recipes to get important K2SO intermediates (e.g. automation cores) to make the planet easier on K2SO playthroughs)
3. Add a new, Rubia-specific recipe to get electric components (this would also enable local module crafting, but since the Rubia mod author did not add this to their K2SO compatibility code, maybe this is not compatible with the original mod vision/theme)
4. Make the tech cards craftable in an other machine (e.g. the Biorecycling Plant) which is available on Rubia already before cargo drops (I think this would be a bad fix as many other machines have more than 2 module slots, so it would be more OP than the original Research Server locked recipe and it would be against the K2SO way/design too, I actually did this fix temporarily and then removed it to get out of the soflock locally)
