Limited content on the new Muffin Builder!!
I have the following problem with the new Muffin Builder: almost the half of my content is deleted from the new Muffin Builder. It seems that there is a limit of content which is a disaster! The half of my content is gone after I save the renewed page. There appears also a warning after saving the page that the page cannot be updated as there is an error.
I started another page from scratch as I thought the page is broken but after saving the new page the same error occurred and the half of my content was gone.
Please fix this issue for the Muffin Builder.
From this Screenshot you can see how it looks like if the page is broken.
