[FactionHeir]

Note the feature list does not include fixed items such as shield bug, tower bug and antitraits, even though they have been fixed too. Maybe too embarrassing to list?

[Nebuchadnezzar]

People, you may want to edit a few of the turn based gunpowder ancillaries (explosives, roger bacon, meister eckchart, albertus magnus) so as to be available to governors after the "gunpowder discovered" event. For some reason CA forgot to update them after changing the event date so at least one can never occur.

or you can set it back to pre 1.2

Edit: What was I thinking? Corrected the explosives ancillary

[FactionHeir]

Actually all three named ones you listed as they require buildings that can only be built after gunpowder is discovered. Good catch btw. Should note though that this only affects new, not old campaigns (i.e. those from 1.0 or 1.01) whose event dates among other data does not get updated to 1.02.
