I noticed this am that WAU is not updating addons beyond Manufac in alphabetic order. If you try to select them individually it still does nothing. However if your reverse the order it updates the rest of the addons starting from the last addon upto where it left off. I have all the preferences set to false and I update without externals. I also unselect show groups. This is something new since earlier yesterday it was working fine.
Try skipping Manufac then, looks like it's hanging up on MAnufac and stopping, probably Manufac is missing a changefile
it's probably the new MCP fault
Works ok for me. But i dont have manufac installed, or mcp for that matter.
