1 is an error due to the showcase file by the sound of it. cannot recall anyone ever reporting such a message
2 cant comment on. I use my memory
3 I get this too. It is a bug that is known and being worked on.

As for errors, I have not had a single crash for god know how long. Are you patched up to 1.033 Lefty? I found SO3 became solid as a rock in my game after that patch
