it seems like this Mod is broken with Krastorio2:
Both mods overwrite Nuclear fuel reprocessing, and at least for me, KS2 wins.
So if I enable both mods, there is no way to gather plutonium at all.
I just ran into this - the fix needs to come from SE2 as it just overwrites the recipe and thus the plutonium is lost. I'll see if I can work on a patch tomorrow.
Here is a patch for this issue - it restores plutonium generation at a rate inverse to tritium generation, but always at least 50% (as a nod towards future proofing the balance). Let me know if you have any feedback!
