Yes, MGS has been having stats issues since late last month. Fortune Affiliates was the first program to publically admit this here:

Tami stated:
The Microgaming systems issue started on January 16th and will therefore have an effect on January’s stats which in turn affects the payments. The payment run for January was stopped as the data which payments are calculated on is incorrect; currently it looks as though earnings and, therefore payments, for January on the whole may actually increase for the affected affiliates.
As soon as MGS has sorted out the data issues the payment run will commence and the stats engine will be switched on – please keep an eye on your inbox for notification of this.
Please accept our apologies for the inconvenience caused and we’ll notify you shortly.
Other Microgaming Partners have confirmed this in private conversations with affiliates. We are being told that a fix is under way.
