derailvalley Jobs no longer completing

[KyuSiik]

Heya, recently tried installing some mods, since doing so I'm no longer able to complete jobs. Whenever I do, it gives me a complaint saying that some car(s) are not on the appointed track. Even though they demonstrably are. I don't know what's causing this issue or how to fix it.

 

The mods I currently have installed are as follows:

Zeibach's Air Brakes and Realistic Steamer Overhaul. The hand brakes mod and supergauges (so I can get an accurate air pressure reading)

 

Any help would be appreciated
