I think he's referring to the bug that enables all assists in Pro Season mode and you can't turn them off. I have the same problem, I think that one of the devs on CM forums has acknowledged it and said that they are working on fixing it.
Same problem for me on PS4.
Anyone solved it yet?
I just read that if you start over and over a new pro season it eventually works. I'm at the office for the day so can't test it for the moment. I would appreciate some feedback on it.
I have another Pro-Season problem. In all Q2's I can only run 100 KG's of fuel. Now I don't think thats like in real life, but the biggest problem is that the competitors aren't doing it. Has anyone faced this problem?
Edit: Saw a tip of creating a new save file, first time didn't fix it but trying it a second time got it all turned off for me, just in case anyone else has the issue."
Notice that he did it twice before it worked. It worked on the first attempt for me.
Finally I'm on PS4, for those wondering how to delete a profile: PS4 menu, navigate to [Settings] > [Application Saved Data Management] > [Saved Data in System Storage]. From there, Delete then f1 2015 and you delete the profile.
