So recently, I uploaded a game called Yoshi CPS Spacebar Test. I then logged out and checked and it wasn’t there. I then unshared and reshared the game and then I checked again and it was there. What was happening???

Oh yeah, the link to the game:
https://scratch.mit.edu/projects/943931691/

I can access it fine, so maybe it's a problem on your end. Try checking your internet speed.

It’s because I rereleased it that it’s there. Why wasn’t it in the first place?

Other proof as well: I had to log on to another account for a school/work account, and for fun I check my own profile. My game wasn’t there, but then I logged back onto mine and reuploaded it. I then logged out and checked my profile — it somehow appeared out of nowhere.

The page got cached with the project, but the indexer didn't actually index it yet.

Though that's a guess since I doubt you cleared caché at all, so that definitely isn't the case.

What’s an indexer?

In object-oriented programming, an indexer allows instances of a particular class or struct to be indexed just like arrays. It is a form of operator overloading.

Not like I know how to clear caché

In most computer-based web browsers, you can open menus used to clear cache, cookies, and history, by pressing Ctrl-Shift-Delete (Windows) or Command-Shift-Delete (Mac).
