Well the SDK 3.2.1sdk3 is not stable.
Besides these errors I reported, I just had a situation where the StateManager forgot an AppState, i.e it could not be linked to in any way and did not show up when trying to add it as an import statement.(causing a cannot find class exception)
Creating a new reference, initializing a new object, restarting SDK, nothing worked period.
I finally gave up and ran the exact same project, unchanged, with SDK 3.1 stable and had no problems.
Thereafter, I reopened the same project unchanged in 3.2.1 SDK and its all back to normal.
I also just had the
component must be showing on the screen exception just by maximizing an editor pane without even running my game.
My stats are under my logo.
