Menu Manager broke in 3.3.0

[Draxeiro]

Well after you submit, it is failing, but you are not getting an error or a success notification at the top.
Which suggests to me that the plugin has to be erroring out somewhere, or skipping an entire piece of logic.

so I am wondering if your page source after you submit and get no success, if you page even got that bit of coed back i pasted above.

I realized I didn't get back to you on this:

After making a change on the Edit Navigation Structure page and saving it will first not view the page source, saying the page has expired and the document isn't available any more, upon reloading the view source page it will show the code.

Compared it in Winmerge: exactly the same. So nothing at all is added.
