On one of my network sites (using WP multisite), the page tree view will show the start of an infinite loop - each page dropdown has a list of all the pages inside of it instead of its child pages. Trying to drill down more causes it to never load. On occasion, the tree will never load at all (perhaps related to the database call - it looks like it just continues to loop through again and again and eventually overloads).
I've tried disabling all other plugins but to no avail. This plugin was working before the latest update.
