On the website, when viewing your account, I've noticed that the account seems to update in a two-step process, and so after a stay takes place, you'll often see your point and night totals jump without a corresponding stay showing up on the detail list. A few days later, the stay itself will show up without a change to the point/night total.
Now if either of the two folks above who noticed the changes in their account didn't have a stay(s) that corresponds with thenumber of nights their total jumped, then I'm at a loss.
