[2.0.9] Rails misaligned after upgrade

[BlandMan]

What did you do?
Tried to change the route of a diagonal track. Deleted existing track placed in save game created in 1.1.110 by right-clicking on sections to form a break in the line. Clicked the green arrow to lay out a new track section, moved the mouse to where I wanted the track to go. Same process I had followed many times before.

What happened?
The track no longer aligns. There is an offset of the entire track section and it cannot be made to fit. The only work around is to delete the entire section of diagonal track and re-create it. The problem doesn't affect horizontal or vertical track sections, only diagonal.


What did you expect to happen instead? It might be obvious to you, but do it anyway!
Expected the rails to snap into line as they always had before.

Does it happen always, once, or sometimes?
Happens every time. Possibly related, the minimum radius of 180 degree turns has also changed.

Log file attached.

I've tired this across a number of saves to make sure it's not a one-off problem.
