Trouble saving custom fields with 3.4.2

Just upgraded to 3.4.2, and might have uncovered a bug.

Using chrome, when I enter a custom field, the ‘Add Custom Field’ flashes yellow and jumps to the bottom custom field in the saved listing, but the one I am trying to save doesn’t record.

If I press “enter” on the keyboard, though, when the cursor is in the new ‘name’ field, the custom field will save. It refreshes at the editor, though, rather than does the yellow flash like it used to.

Lots of plugins that could be causing the problem, but wanted to check in if anyone else was having this problem before I dive too deep into troubleshooting.

Thanks in advance.
