Vassals won't improve holdings?

[Penta2]

OK, so....As William the Conqueror, I just finished conquering England.

This always happens, however...I hand out titles, and despite cheating to amp stewardship up to 100 or so on all my vassals...They never improve their holdings, despite having gobs of money.

Is there a way to "encourage" my vassals to build on their holdings, or do I have to do all that myself before handing over the keys?

They should be upgrading them slowly over time. Do they all have huge stacks of cash and aren't spending it? I'm pretty sure its just slow at game-start, especially if they only have 1 county.

What do you consider "gobs of money"?

I modded the save file so each vassal had 100k gold, for the record. No building.

Have you tried playing the game without cheating? Vassals will always build up their holdings once they start generating an income.
