Chat plugin breaks BuddyPress group edit

Wordpress 3.6
BuddyPress 1.8.1
BuddyPress is the only active plugin

After I activate Wordpress Chat if I go to Groups in wordpress administrator, edit a group and click save it says "Are you sure you want to do this? Please try again.". If I de-activate the plugin it works just fine.

I deactivated all of my plugins and went one by one to find this was the plugin causing an issue.

Anyone have any ideas?
