There's a little glitch with the combat tutorial. When you first get into a fight, it's meant to pop up a little window explaining things. It does but there's a catch - it's when you created character gets into combat, not when combat begins in general, so if your character is hiding and the others get into a fight, it doesn't show you the pop-up. It's only if your character breaks stealth that it does. It's just a small thing but something worth fixing before release.
