I have taking to driving the 143 on RSN alot lately as I find it nice a relaxing. Anyway after going back to the game since Hamburg to Lubeck released I now find that the AFB on the 143 is crazy. I have not bought the DLC but I have noticed the 143 behaves very differently since this DLC released. On RSN when leaving a station I set the traction at the usual 100% and AFB at 40km/h, the 142 that accelerated rapidly up to about 55km/h before the power drops back down to suit a 40km/h cruise speed. This is on level track and has never done this before. It happens all the time now so I can't drive the 143 in any sort of realistic way any more. To me now the 143 is completely broken and basically unusable. I don't know what patch or update broke it.
