Timeline problem when going from 3.0.14 to 3.1.0
When you update your hippo you will notice that your old timelines are acting strange and changing the geometry, it will rotate your content 180 degrees.
That is because in 3.1.0 the rotation is set to 0, and in 3.0.14 it was from 0 to 360 so the level was 180.
Here is the workaround I got from the GH support
Load 3.0.14 (same version as the timelines) and then upgrade to 3.1.0, this will update the timelines to 3.1.0.
then you will have to uninstall 3.1 and then do a fresh install to get the GUI back again.
