Playing some multiplayer today with a few friends and noticed a few problems.
My progress towards leading 50miles in multiplayer races is at -2 (yes minus), where I know if been in the lead for at least over 50 miles. While at the same time my friend unlocked the 50 and 200 miles in the lead within 3 1/4mile drag races, and also is 90% towards the next achievement in the lead.
Is this a known issue or just a lucky glitch for my mate, and tough luck for me.
The drag racing seems to boost these badges, I did the drag on my sons account to get me the tuner and artist badge. as this was only way I was gonna get them, a 1/4 mile counts as more than 1/4 of a mile for some reason. as for -2 miles not sure on that one. Try setting up private online race drag 1/4 mile against ai put it to 10 heats,win every heat, then back out and see what it says.
There is definitely an issue with the lead miles for multiplayer - the drag seem to count way too much as has been mentioned and at the same time my progress for the 500 and 1000 miles achievements have gradually decrease to the point where they now read zero - which is impossible given I have the previous achievements.
