A customer can now hold two paid copies of the same class package and get the places they paid for from both.
- A second copy of the same class package - for example an admin-created plan plus an online payment, or one copy for each family member - now books its own places instead of quietly booking nothing.
- This also applies when a copy is set to book only sessions that have not started yet: it still books its own places on those upcoming sessions, and never on sessions that have already started.
- Subscription renewals are unchanged: a renewing customer keeps the places they already hold and is not booked in twice.
