But 3.X still supports old-style scripts and non-object-based scripting, it's just no longer preferred. I know this because my game uses both of those and it still compiles and runs under 3.X. Let me paraphrase: the game appears to run just fine in 3.X; however, I have not tested every single interaction within the game. I'm looking for certain corner cases in design that are known to sometimes fail (and it would be nice if there aren't any), so that I can specifically test those. I already know that the common parts of the main script run just fine.
