4 Away fixtures in a row??

Thanks for raising this to us, the QA team will take a look into it a bit further. Depending on qualification for other competitions such as Europe, and progress in the Carabao Cup you could have additional midweek games during October as well. But I don't think there is anything that prevents a run of away games but I could be mistaken.

We've had a look but wouldn't consider this a bug I'm afraid. 

While 4 in a row is uncommon, it is very much still possible, and as such it's something that's repeatable in game.

Nevertheless, thank you for taking the time to report this to us.
