Why every time I download a game or anything else from itch.io let's say it download until 97.85%  and then when the internet slows down or it turns off and then turns on the game start downloading over from 0% or it says restart downloading but lets I downloaded an app or video from another site and let's say that app downloaded until 90% and when the internet turns off then it on the app continue downloading without any problem. /* Note I am using Internet download manager and I get this problem just from this site. Please try to fix it and thank you for reading my comment. Have a great time! */
