Gold gambling NPC broke in act 2 (normal)

Bug ID: 558.706.412

Was spamming ctrl+click on an item on Risu, she gave me two and then stopped working.

Ctrl+click does nothing, clicking and dropping in inventory also doesn't work.
Doesn't take gold anymore, still buys items from me.

Tried resetting game: nothing. Tried loading a new instance: also doesn't work.

Edit: forget it, the vendor has limited stock, just hovered the bottom right counter on the shop UI.
