That's most likely just because the adoptables are updated via a scheduled task. It should run every hour exactly (as in one o'clock, two o'clock, three o'clock, etc). Wait until that time has passed and then see if it hasn't been updated.

(You can, of course, run the scheduled task immediately through the Admin CP if you'd rather not wait to test it - not that said adoptable shouldn't already have been updated now, if the member had enough posts at the time you posted here.)
