horrible, you might well find alot of people around your # have the same issue then
does your xbox show a different time to the web? or just the rollup does not add up to the sum of your times?
does xbox show all your race times? ... not just local.
one thing, if its 2 hours exactly, it cant just have missed a race, otherwise it would be 2 hours MINUS the race time not registered.. so sounds like a screwup where its registered ALL your times but still has one penalty left (odd logic for them to have but there you have it)
i reckon you should push T10 to do a manual adjustment, there devs could easily(!) recalculate your summed up times if they have the individual race times.
(wouldnt be too hard for them to do it for everyone who is within (say) 2.5 hours of top time)
its no where near as difficult as trying to adjust the hotlap times would have been, as you are talking about a single rollup figure (unlike hotlaps which are per class, track type etc)
if they refuse, go kick up a fuss on FM2.com, and they might reconsider
