Got an error on game launch that lab input #9 was the metallurgic science pack rather than agricultural. The mod Nuclear Science adds a new science pack for Nauvis, so it bumps the space age packs up a number. After disabling that mod, the game launches without issue.

Not sure if this counts as a bug per se, but I figured I'd report the incompatibility at least.

Thanks for letting me know! I've released a new version with a fix (as long as the mod doesn't remove the Agricultural or Electromagnetic science packs, or put another science pack in between them, it should work).
