I searched within the search field and showed no such thread of any Achievement issues and also not sure if this is the proper place, but here goes.
Recently played The Goliath with a Forza Edition vehicle with at least 4 laps so I could obtain the achievement, after 3 attempts I gave up… but this evening I decided to obtain the achievement Better get Kraken: Get under 6 minutes in the S5S Raptor… after 2 laps, I have reached the line at 5 min 25 sec. Still! No achievement for that either. My game broken? Am I not allowed to be an achievement junky?!!
