Revealing mistake: Towards the end of the movie, Hockney (Kevin Pollack) looks into a van and discovers it's full of cash. He is then shot from behind and blood splatters all over the money. When his chest explodes, you can see the plastic of the bag the blood was in. (01:18:10)
Revealing mistake: When the police car is set on fire you see from the top that the flames start at three different spots, hood, roof, and trunk. Then, when the three vans drive off there's a shot from inside the police car where you don't see any fire. (00:32:45)
NancyFelixRevealing mistake: In the flashback, when the boy has his throat slit, there's no blood or wound.

Answer: Soze ended up back under arrest and for some questioning as 'Verbal Kint'. He never really vanished, he's just playing two parts/people. He really vanishes off the scene by the end of the movie after he tricks Kujan.
With the exception of what's known to have happened on the dock, the entire story is a lie told by Verbal Kint to Agent Kujon. Kujon realises this after Kint leaves the office but not in time to catch up. The entire movie is about a habitual liar making up a story about what happened on the dock. He may be Keyser Soze or an alter-ego variant but even Keysers rep is subject to question as it was told by the same liar. Verbal himself said about Keaton, "He was a grounded guy, a cop. If you think the husband did it then you're right." He was telling on himself as sociopaths will do when they think they're smarter than everyone around them.
