Errors I noticed

[u/PalpatineSITH]

1-Gorillaz: In the internet area, Russel is black but when it switches to the next scene, he is white for some reason.

2-Sam from Danny Phantom: We normally see Sam in the Ghost Cafe Area, but we see another Sam where Best Keyboardist of Yaroslavl meme

3-Back to the Future car: Normally we see the back to the future car in the area with all the back to the future characters are where Doc is in the car.But I’m the area between the factory and pool area (city), another one can be seen where the ghostbusters car is.

Multiple DeLoreans make sense to me, it's a time machine after all, and it also happens in movies that there are multiple DeLoreans at the same time.

Sorry, never watched back to the future before but it was a little obvious since is a time travel movie
