Interesting (in an annoying way). Based on your post, I just logged into both my own and my wife's accounts and sure enough the transfer that we'd had setup and had been working for quite sometime has disappeared from both our accounts.

At the bottom of the page it still clearly says, "You can move your points, but only to another Chase card with Ultimate Rewards belonging to you or one member of your household or owner of the company, as applicable."

Very annoying...
