Has anyone seen/can anyone provide feedback on the below issue? Great tool (JA Page Builder) - we are using it with great success but we've encountered the issue below twice now - occurs randomly):

We build + Publish a Page - everything looks great; all URLs publish correctly/accessible, etc. - All Good! Later, needing to Edit a particular section, we access the Page via Admin>Components>JA Builder>Live Edit but the Page now bombs out, and seemingly corrupts the URL in the database...
the Page will suddenly render as 404 w/URL showing itself leading into "edit" mode for JA Builder (ref attached image "jabuilder-404.png" - not the "?jub-edit" call at the end of URL)
checking the Menu Item for this Page, all the IDs are correct - the Page is mapped to the Menu/the Menu item points to the correct JA Builder Page (reference attached images, "jabuilder-page2menu.png";"jabuilder-menu2page.png";"jabuilder-menu-mapped-to-page.png")
AND we can even still see the actual Page by checking the "Menu Preview" (reference attached image, "jabuilder-menu-preview.png") - the Page is still there from the menu Preview, but JA Builder is somehow disconnected - is this a hiccup in SQL? It's happened twice now randomly, it feels like it temporarily blips on db call and corrupts the URL but I'm not entirely sure...

Again just to rehash:
the JA Builder Page originally created just fine - only later going into "Live Edit" the Page suddenly returns a 404 whilst still being found/seen from the Menu Preview. The trigger for this happening is "Live Edit" - somehow the call/url gets corrupted.

Any ideas anyone? I'm getting ready to poke through the Database now just thought I'd tap into Forum resources in case someone has seen this themselves/knows what the issue is - i didn't see this asked anywhere prior.

Thx in advance for the Help!
