Since the release of the DB BR 101 "Expert" and the associated "Bpmmbdzf 286.1" the seating position in the "Bpmmbdzf 286.1" is bugged - the driver sits sideways. It would be great if you could fix this bug, which has existed for almost a year.
The development of TSW 4 was discontinued with the release of TSW 5. In addition, TSW 6 was announced today, including a free starter pack, so don't expect any fixes or patches for TSW 4.
