Title says all.
I am trying to withdraw 3 refined but an error shows up saying I need to withdraw to the nearest whole refined. I tried blocking and unblocking the Vault Bot, I tried friending and unfriending as well as switching Vault Bots.

I think some users with a lot of credit has withdrawn at the time and the bot ran out of metal. I have been refilling it and that error should no longer be here.
