I have a gallery let's call it 'Kids Kung Fu' under the Category 'Family', Subcategory 'Children'. Normally the breadcrumb trail for this gallery would indeed display the category and subcategory. Since I've added this gallery to an Event I created, this is no longer the case. Whether you access this gallery through the event URL, or by clicking your way through the categories, you'll wind up seeing a new breadcrumb trail that points back to the gallery.
Breadcrumb trail before adding gallery to an Event:
me > Family > Children >
Breadcrumb trail after adding gallery to an Event:
Event Name > Gallery Name
In both cases the URL remains the same. I prefer to have the breadcrumb trail remain as it was before adding this gallery to an Event - is that possible?
[UPDATE] I think I just noticed when the issue is happening... As a guest, with the site password, if you visit the Gallery before you ever visit the event, by navigating through the categories - you'll see the first breadcrumb trail as I'd expect. If you visit the Event's gallery, you'll see the second breadcrumb trail leading back to the Event page - I'd expect that too. However - this is when it seems a bit buggy - If you've visited the Event, and you later browse through the categories from the homepage (or just directly to the URL) to get to that same gallery, you'll see the second 'event-style' breadcrumb trail. Think this is a bug? I'd expect in the second case to see the first breadcrumb trail.
