I have sometimes the same problem when the scrap outlines are drawn a bit far from the last station...

To help to reproduce the problem, I have made some test  :
If you remove the point station -name 22.1 in the scrap, the behavior seems ok. Why ? Don't know...
If you remove the point station -name 1.3, the behavior is not ok but different

original data :

without point station -name 22.1 :

without point station -name 1.3 :

Hello,
i fiddled more with the data, but to no avail.
It seems its something in lochs extrapolation code using misaligned data or something...

Is this reproducible at your setup?
