Santa Fe Type 2-10-2 brake bug?

[Stigah]

Hey!

I bought this route when it was first released, and played all scenarios without any issue. I found a pack of new scenarios which I have downloaded.

Now I'm having some issues with the 2-10-2 engine. I have almost completed the scenario, just one or two task left. For some reason, I'm not able to move my train. Put the regulator to 15% and the wheels start slipping. I manage to get up to 5 mph, and when I put the regulator to 0%, the speed drops to 0 right away. Handbrake not applied, and brake cylinder pressure is 0 PSI.

Is this a known bug, and is there a fix for it?

Thank you!

Can we have a bit more information please, route, scenario?

sounds like bad physics / horribly high drag coefficients.
