Fortnite installation restarting to 0

My fortnite installation was on 5% when i left it this noon cuz of school so i had to turn off my laptop but then when i came back and resumed i was confused because it was on 0% i thought it was just catching up but it took a whole hour to get a 3% and now it’s on 17% and i’m scared that turning off my laptop cuz i have to sleep will get me back to 0% tomorrow morning and getting me to 100% is just take too ■■■■ time. we don’t have the best connection btw.

try keeping it on a charger and waiting if its really important to you otherwise, i dont see a way around this.
