Hi,
I just bought the WookTickets plugin a week ago so I am not really an expert on this, but I would like to report a possible bug.
I was trying to add a custom text retrieved from WooCommerce order_id to the ticket email template and for this reason I hooked to the action
tribe_tickets_ticket_email_bottom
In the file the-events-calendar/src/views/email.php I think that is missing a parameter to the action.
I changed this code
do_action('tribe_tickets_ticket_email_bottom');
in this way
do_action('tribe_tickets_ticket_email_bottom',$tickets);
and now I am able to retrieve the information that I need.
