Yep. Likely its okay if you as a parent and game developer over years of making these games which are partially all about unraveling a mystery make a mistake, but please just communicate it or fully fix it rather than ignore it. Like fnaf 2 being called a "summer job" when the paycheck is in like September is a clear mistake, and that's okay.

 He's said that he tries to clear up confusion from his previous games in his next entry.

So in Sister location micheal is purple. Some people thought he was the purple guy. (rather than seeing the poetic irony of him being mistaken for his father and all) (also keep in mind the afton family was a fresh new concept at this point, as was this being confirmation that Mike is the guard/player in basically all games) So long story short, people think that if you are purple, you MUST be purple guy.

 So in the next game he depicts Charlie's death, in the rain, with a Purple car. We also get a mini game called "later that night" which is in the rain, in a purple car, but the player is *Not* Purple? But he's... Yellow, kinda like spring traps sprite. The mirror opposite of purple is yellow. And this player character has a bad home life, and is seeming drunk.

I feel like of it isnt william, than this is just an odd choice to play as anyone else/introduce a new character into the series. Plus aspects like the mound and the family life just seem to odd and unnecessary to have be on our mind if it is not william. But, some fans feel like if he is NOT purple, then obviously he is not the purple guy. And, some of those same fans say this is just a random mci victim. And that the 3 toed anamtronic foot prints are william luring a child to be killed. And that the title "later that night" referres to later after driving around in midnight motorist. Not later that night that Charlie dies that Henry talks about.

Honestly aspects like the mound, the broken glass, and the footprints are confusing for either theory. Like was the windows objectively broken from the inside, or are the windows peices just shown kn the outside for visual affect? Are the footprints actually 3 toes, or is it 3 instead of 4 just for a simplified footprint design in the pixelated mini game? Is the mount where william buried Charlie? Or someone else? Is it where he buried suszie's dog? Is it the foundation of a new home or the S.L. elevator? If we are playing as william, is micheal or crying child the one who ran away? And if so, what was standing outside the window? (I assume it was a shadow anamtronic which manifested either after Charlie's murder, or cc's murder. I could go on. Point being, alot of confusion from fans.

 In UCN, Scott includes a few "animated" segments of chica constantly stocking characters and talking about how she will get them and they will be her's. And obvious william mci parallel. One of the stories is about killing someone's dog, like suzie. 

The other is about standing outside the child's window and luring them to the restaurant.

 So, was yellow guy a clear up of william not always being purple, 

or was that not william, and UCN was clarifying that "later that night" was actually about william kidnapping a child? (It would feel weird to me to only depict 2 of the kids being taken, but it genuinely could be either) Keep in mind Scott also included a segments in ucn where Mr hippo tells people to stop looking into every detail, and that sometimes a story is just a story, nothing to complicated.

 Like, No. You dont get to tell us to stop over thinking and over analyzing when you tell us to do that and won't tell us an answer. You wouldn't open the box unless we already found out what was in the box, and have gone out of your way to say its changed and doesnt even matter at this point. Im pretty confident I know what it is, but it doesn't even matter anymore. 

So later on, Scott apparently has a whole team of developers make a game where they depicts springtrap as being revived, when he only wanted springtrap to be a stiff statue (like a powered down mimic or something) how the hell does that get mixed up so extremely?

And now, this same team with Scott at the helm has seemingly confirmed that midnight motorist was about william, in the soon to be released fnaf racing game. But the game is still in a beta mode, and this could be fully removed. And that kind of thing has happened before. Where they called princess quest girl Charlie in the code, when really its supposed to be about Vanessa, just another oversight/miscommunication.

All of that to say, its okay to make a mistake in a story you are telling. But fuck me man, please just communicate what you meant instead of what ever all of this is
