(Definitely NOT) a Major Bug....

[Mike from CT]

The Peco N scale Code 55 10 degree crossings, and single and double slip switches share the same  flaw in AR that is critical -  if anyone actually lays track accurately enough to worry about deviations of less than one hundredth of an inch....

The attached drawing shows the problem - a horizontal track comes out .01" (or .22mm) off.

To reproduce from scratch in Version 4.26:

1) Select any of the problem tracks (10 degree crossing geometry - single slip, double slip or crossing) and place on layout.
2) Select either of the left end points and set angle to 90.
3) The Y coordinate on the right side of the horizontal track will be .01 inches or .22 mm off.

Yes, this has to do with the length and width and the angle of the item.
It's mathematically impossible to define it in such a way that all of these three are correct given the item as it is produced. Of course, in practice, you won't notice this, but in a software program you do.

It's the same problem with many of the curved turnouts such as Fleischmann's.
