Menu Manager broke in 3.3.0

So sounds like a plugin issue above certain pages on your installation.
This issue appears on 3.2.3 as well? can I close this as it sounds specific to your install.

It is still not that much data to save, also errors like that usually make your page request timeout.
And you should have an error in your gs error.txt or your hosts.

I wonder if you are getting a js error.
Try checking your browser console, F12 in chrome for js errors when the save fails.
