Regarding the family gold loophole:
To clarify precisely what was going on, it got brought to the attention of the devs because certain families had drained their coffers to a degree that made everyone on the dev team sit up and go "what the hell?" simultaneously. Was kinda funny to watch, actually.
Asking your aunt at your family home for gold did not, previously, have an effect on your balance with your family (which determines things such as H/P losses for calling family assistance, and the point at which they stop sending you funds). Family wealth also regenerated (relatively) rapidly on its own below a certain point. No one had previously envisioned what it would look like if a large number of characters had their family home in the same place and systematically gamed the system in this fashion. What it ended up looking like is penalty-free gold to the tune of four, possibly five figures, that kept regenerating.
As has been explained elsewhere, coders can't fix problems until they realize a problem exists. No one had imagined that these features could be combined in a way that was clearly detrimental to the game, and as soon as it was noticed measures were taken to correct that. The measures should have no effect on anyone who isn't already at the limit of what a given character can take from their family.
