Fortnite ps4 29.128 GB?

I'm currently downloading version 2.60. On the ps4. However, it says that it still takes 70 hours and that it has 29.128 GB! Which can't be, since the internet says that the new update for Fortnite only has something with 3 GB! It can't be right?

Is nh buck delete download and download again

If it says it will be right or a mistake. I guess it says 2.9128 GB

OK.

So I've done now. Now it's 11.958 GB! And if I generally want to start it without an update, then after a while the loading screen shows me that the data of the following application is damaged. And that I should delete it and download it from the library! What shoud that? I also had Star Wars battlefront 2

Fortnite is downloaded from the store, so no CDs or something
