I recieved this message when I wanted to play BNSF V-Cloric on Tehachapi Pass! "Play the whole without using save or it might affect the breaking". Or something close to this. Should there not be a fix for this so you can use save whenever you want?
There was an issue with the original BNSF locos where the train brake wouldn't release 100%. I replaced those ones with another model to overcome the problem.
