No, you definitely don't and I just double-checked that the changes made it in. Assuming that you did update to -RC6, this sounds like it'd probably be resolved by a clean reinstall of the game (by saving off your saves/mods/screenshots folders, deleting the game folder, and then running the installer). I suspect that somehow some of the game's files failed to get updated by the reinstall overtop of it - it doesn't happen often, but it does *sometimes*.
