From a quick skim of the newer files and collected from elsewhere.
1) Honor discipline policy still lists at 15%, but is providing 20% bonus (easy to fix). Disregard
2) Knowledge opener isn't adding +1 science to science buildings as intended. (again, easy).
3) Capital RR building is providing both a RR connection and +25% production (ie, 2x what is intended from the building). Removing the +25% production on the building should now be fine. Related: using wealth/research processes doesn't update for the RR connection bonus to the capital in other cities. (if you are running wealth/research when the city is connected, it doesn't notice that it was connected by rail or lighthouse).
4) Subs attack bonus is duplicated at 25 and 50, the 50 bonus is incorrectly removed (typo).
