Something Is Installing, But What?

I was playing some TSW2 on my Playstation and I noticed text saying Installing... in the top left corner, it stayed there the whole time when I was playing. Can someone explain what it was installing?
I was not installing something.
This was on PS4.

 

possbily the 9th of feb update

 

I doubt it's a patch update as that requires a restart to install. Do you own any DLC and if so, is it installed and useable?

 

could it in relation to the 64g limt?

 

Possibly but can't say I noticed it when I exceeded the limit or when I swap routes around (though my memory isn't exactly brilliant)

 

i only can think this is why

 

It was on the PS4, so there is no limit issues.
I already updated it to the newest update.

 

intrestting have you purchases something recently

 

My PS 5 says that when I‘m playing the game while an update is downloading. When I exit the game and restart it, it goes away.

 

It lacks ram, so since it never installs completely, from each start of the game. start again

 

Installing various cat related sound effects for locomotives.

 

Could it be installing something not related to tsw2?

 

No, otherwise the Playstation would say something is installing, not via a game.
