Can't add event tickets after save

[jorgeolothar]

If you try to add tickets in the event edit form, one at a time, it will start overwriting previous event tickets (at about 7 distinct ticket rows). Even after deleting and trying to re-add tickets the problem persists.

Only way I've found to fix issue id to erase all (relevant) event tickets in the DB from ppSD_event_products and ppSD_products, and add more than 7 tickets all at once in the event edit form.
