Compile Aug 3 2018
Engines half way up a slope turn around in opposite direction or get stuck . cars just get stuck

Will investigate this bug later

Its an old pathfinding bug due to inaccurate calculations with the slopes and sloppy pathfinding.

It's fixed in the rewrite but I have no plans on fixing it in the port. More work than I think it's worth, when a rewrite is later in the year.

But if you or someone else wants to fix it, feel free to do so.

This is something else . My compile from July 20 2018 , Traincraft-4.4.0_016 , does not have this problem
something has broke in the last 14 days

I'll go through the code and see what happened

nothing changed inside the RollingStock since 18 May.

The problem starts with 9c1701f
reverting back to previous code fixes issue
ill take closer look later
