Edit: It looks like it's exactly the average of Charisma and Beauty. Before I think it was weighing mainly on Beauty alone, as +charisma items weren't seeing as much of a looks gain as a +beauty item. This is something I'll take into account for balancing item prices.
It has always been an average of charisma and beauty (at least since I started playing anyway, back circa 1.25). You probably weren't seeing much of a change from +charisma items, because charisma is trainable. If you train it to 100, +charisma items won't have any effect at all.
Currently, it seems as though there is no way to use items which have been created in the item creator to affect all girls temporarily. I give one to a girl, tell her to use it, and nothing happens. The item doesn't even go away.
The "affect all girls temporarily" items have never worked to my knowledge. I don't know if Necno implemented the system and it just doesn't work or if it's a "to do" thing.

Another "not really a bug but should be fixed eventually" report: Some of the locations where money appears in the game are missing the currency unit (in this case, gold). Locations I've found so far are:
- The main screen, brothel's profit and player's cash.
- Staff screen, total cost of gangs, matron is missing cost information completely.
- Town, new brothels purchase dialogue box
- Supplies/upgrades: daily cost of advertising

I have a screwed up save, which occurred just after my first daughter matured. Save attached.
