I've been having some issues with using PageBuilder modules and saving.
If I create a new PB module or edit an existing PB module, add/change content, then hit Save & Close it often returns me back to the module list view with an error: You are not permitted to use that link to directly access that page (#450).

Sometimes if I hit Save, wait for it to save, then go to the ... menu and hit Close it kicks me back out to the module list view instead of back into the module settings.
Also, it breaks Advanced Module Manager (seems randomly when saving the module) and the only way to get AMM back to loading properly is if I re-install it.
