Seats and Tickets Cube hasn't processed since 15.1.4

Question for admins who self host and are on 15.1.4:  has your Analytics load successfully processed your Seats and Tickets cube since applying this service pack?  We applied 15.1.4 over a week ago and this cube (and only this cube) has errored consistently since then.  Our TAMATO users miss having up to date results in Analytics.  I have an open help ticket but it hasn't had any movement in several days.  Thanks!
