If a bookable product bundle contains other bookable products and one of those products becomes unavailable because of the bundle being booked then the single product also shows the unavailability on those dates, however an unavailable single product doesn’t make the bundle unavailable – I think it should. Do you have a fix for this?
I’ll have a look at product bundles today, because there are also issues with discounts apparently. They seem to have changed how the bundles work in the latest versions. I’ll keep you informed as soon as possible and release updates if necessary.
