Many PC users are reporting download issue with the Forza Horizon 3 preload. Users are reporting Forza Horizon 3 downloads reset issue for no reason. Problem is that the game download size it 49Gb and many users have paid extra for four days early access.
For some users, download progress is reset to zero after resuming a paused download. For others, it happens on its own as the download approaches completion. Others still run into problems when Windows 10 installs updates, interrupting the download. It’s not easy to redownload entire game again as some people have data caps, while others have download speeds that make this task a multi-day time investment.
Microsoft is aware of Forza Horizon 3 Preloading issue and working on the fix. Early access for the game is coming tomorrow, September 23 and public release for PC and Xbox One on next Tuesday, September 27.
