There seems to be a conflict between Wordpress 4.2 widgets and the WPMU Dashboard. When you try to move widgets around on the widgets page, they move to the top and only right to left vs allowing you to re-order them. I went through the troubleshooting process and moved the folder [wpmu updates] to a folder outside of the [plugin] folder and everything started to work again.
Additionally, I am having a challenge seeing widgets that have been configure with the Jetpack visibility to show on bp member pages. They are not showing. When I disable Jetpack, they show. not sure if this is a compounded issue. I am currently using BP Multi-network and can't seem to isolate the challenge.
