Heyyy ! 

I think i have a problem with mouse sensivity in Fortnite, when i put 0.1638 in savefile and i launch the game and i comeback to savefile, it's put '0.6952039' not '0.1638', it's normal ?

Thanks !

Did you export it to cloud after you saved it?

I open ClientSettings in : C:\Users\SuuWhoop\AppData\Local\FortniteGame\Saved\Cloud\7dd843c4d48a41bfb92b354ccdfd87c6

I just change the sensivity and save it (with ClientSettings Editor).

After save you need to select Cloud Export and enter your credentials so it syncs to the cloud. Fortnite always reads the file in the cloud and replaces the one on your harddisk with it.

Oooooh okay ! Thanks man !
