I checked my GP account online and saw 5,055 points were added today in the "Base" column with the description of "Other." There was no description of the activity. I called GP customer service and it took a few minutes on hold to get an answer, but I was told that Hyatt went through my account and saw some incorrect points postings. The net result was 5,055 points added to my account, which I was told was the shortfall. No further details were available.

A big ^ for unexpected points, and for getting one-half of one percent closer to Lifetime Diamond status ()
A big to me for, apparently, not keeping well-enough track of my stay credits.

Is this an isolated incident or something more widespread? If the latter, what could have prompted it (perhaps an acknowledgement of the shortcomings of GP's point-posting system)?

Edit: I guess I can't assume these count towards Lifetime Diamond status, as Hyatt Visa points also post as "Base," but do not (I believe) count towards that status.
