In my case is not the fees but the money not coming in at all. I have now over $200 paid and if you check the blockchain nothing has been sent in over a week. I try contacting them on twitter but nobody replies. So basically running away with the mining results randomly.
It may be paid out honestly the bitcoin block chain is backed up quite a bit. I have a payout on a different pool that has been sitting unconfirmed for almost 24 hours now.
