[Solved] Did 1.1 change turret-top rotation (and some other things)?

[Napoleonite]

Do all turret-top textures now have to point east instead of north? Or did I do something wrong? I couldn't find this in the patch notes but I probably missed it.

Also, my Vector2, Rect, etc. throw errors in 1.1:

The type 'Rect' is defined in an assembly that is not referenced. You must add a reference to assembly 'UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'.

Does this mean we must reference CoreModule instead of the previous one now?

Mmm should we use a different .Net version now?

Warning      The primary reference "Assembly-CSharp" could not be resolved because it has an indirect dependency on the .NET Framework assembly "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" which has a higher version "4.0.0.0" than the version "2.0.0.0" in the current target framework.

The DesignatorDropdownGroupDef doesn't work anymore (it shows steel icons).

Etc.

Also wondering if there is an 1.0 --> 1.1 upgrade guide somewhere already?

UPDATE:
Nevermind, the 1.1 update contains an update guide.
