UPDATE: Bug fixes (v1014)

Today's update includes the following:
  • Fixed a crash when starting a pipeline with too many reactors.
  • Removed impossible scores from the histograms for the "Swapite" journal puzzle.
  • Bumped the version number from 1013 to 1014.
When things settle down with these changes I'll upload a build to non-Steam stores as well.
