Quoting Rhonin_the_wizard,
The only explanation that comes to mind is that you somehow selected 2.33 in the Beta screen.
To go back to 2.8 right click on GC3 in your Steam library, Properties, Betas tab and change to no beta.
I may have done that. I am still confused about 2.33 being in beta when a newer version is not.
Anyway, thanks for your help and fast response,
Richard
