We'll have to wait for the OP to post more details about this "bug". Although I'm still not convinced there is any bug at all, well you could have even "Inspect element"ed it, it is a bit hard to believe two newbies posting about a bug without any trusted member confirming it.
I can confirm that there's an issue. Withdrawals were not processed correctly. We are aware of what went wrong and will correct it ASAP.
