5.5.1 Bake is stuck but baking turned off and other issues

Why is this half finished baking job shown in the bottom right of the editor when I have disabled all fancy lighting effects and GI Baking, so no baking is required?

I close the project and re-open and it is still there!!

Not everyone uses light baking Unity

I see the same thing happening on Unity 5.5.1 OSX as well.

Also in 5.5.1 when I go to compile standalone windows it just locks up the editor for a minute or so while doing the initial build which at first I thought was the editor crashing but it is just that it now lacks any progress message until well into the build process.
So on the surface 5.5.1 is a step backwards (still trying to move on from 5.3), I only hope it is better underneath.
