Happened again, boy this is a rare bug, it only seams to happen on 1 page out 8 sites we do. This bug happens just enough that it has us concerned.
clients are loving the sites we build in the builder. awesome plugin.
we haven’t had any bugs scene the 1.3.8 plugin and today we got 2 
I have been watching the process alot closer than I have in the past and can actually duplicate the issue on one of the site on the 1 page that has the bug.
little back story: (not sure it helps) your templates are great but there not quite what we sell our clients on, so we have a dev site that we have been creating new templates on, we are up to 25ish and adding more each week. on the dev site that we have created the templates on, we have never has this bug happen.
also a nice thing happened on 1.3.8, when this bug dose happen I have noticed that it now only kills the row its on and not the whole page like before. this has been nice, as I can now save alot of the work done by creating a new row and not a whole page.
again our process, we create a new dev site, upload WP through cpanel, then login to WP, upload the newest version of beaver parent and child, activating the child, then go to plugins and upload and activate the BB-Plugin, then we install and activate the bugherd plugin, then the last step is to upload the template xml file through wp uploader under tools. then right into creating the pages and content on the pages through the builder.
back story done 
site 1
first page on the site, went into the builder and selected one of our templates. Went to edit all the header modules, all the popups showed as blank popups, once the errors are turned on, I get 8 notices and 1 warning.

site 2
same thing, but as one of the last pages on the site. selected one of our templates. duplicated the pricing module just fine. duplicated one of the header modules and moved it, then duplicated it again, this is when I believe the bug occurred. because after this last duplicate any change after this didn’t stay and reverted back to this point. no php errors like in the past and if I delete the rows the problem headers are on the page looks to be savable.
now the fun part, I have duplicated this, only once so far and only on this 1 page and only with the headers module.
the process for the duplication. delete the header and rows that the headers, the row is full width and only the header module is in that row. now add in a header module at the top of the page, take care not to add it into the pricing module row thats is there now, force the header module to make a new row above the pricing module. now add in the header content and save. now save the page. now duplicate the header module, and move it down inbetween the 2 pricing modules, taking care not to add it into eather pricing rows, force the system to create a new row just like the top one. now save the page, the header module is in the wrong spot and after this I cannot change it.
I am noticing that it seames to only happen on one of our imported templates and only happening in the header module.
again thanks alot for being patient with us, as we work our way though this 
as soon as I can get logins and ftp set up for these 2 account I will fwd them along
