I just bought this and am disgusted with the lack of a doppler effect of the prime mover. It is the only DLC I've ever purchased with this flaw as the prime mover sound remains at the same RPM whether approaching, arriving, and passing. What kind of QC was done by DTM prior to release and who at DTG failed to notice something so obvious prior to putting on sale? I am thinking of a refund.
You are better off asking DTM directly on their Facebook page rather than posting this here. https://www.facebook.com/Digitaltrainmodel
If you have not used TS2022 for more than two hours since the purchase you can get a refund but if you have use the Game, not this DLC, you won't get a refund
DTM made really great stuff in the past, the UP 8500 GTEL (which was the first loco I played on TS, and still is an absolute milestone in functionality, handling, texturing and scripting), the NS Big 7's just to mention a few, but lately I notice the quality of their DLC is dropping. Sadly.
