Clearing cache is also recommended.
I’ll specify version 1.03 in the PDF.
The “unable to resolve clash error” happens for a nymber of reasons. I am very meticolous when it comes to routing AI and player trains, and i add in more destinations so nothing can go wrong. So if this message comes up it is because the dispatcher dismisses a route i specified for a train. Why on earth the dispatcher sometimes does this i don’t know. Another probable reason is the dynamic allocation of wagon numbers. If two wagons by accident have the same number this gives the same error mesage.
I’ve had this error with qd scenario where there only was two trains and their routes was more that 100km apart. A train clash was impossible but yet that was the error message i got.
Old TS code getting fragile.
