After investigating the issue, we will be removing non-IAP items and refunding players who made purchases for incorrect prices. We believe this is the most fair solution to the playerbase as a whole. Please note that the removal will be applied for ALL non-IAP purchases made during the time window wherein prices were incorrect, regardless of whether its price was incorrect or not.
Given that the affected purchases will include items from Days of Love, as well as the most recent Traveling Spirit for some, we have extended the duration of both to allow players time to make those purchases again (or first the first time) should they so choose. Both will now end on 23:59 February 22 (PST, UTC-8).
We sincerely apologize for any inconvenience this issue may have caused.
