Random one: "extend srf" command almost always broken

From update to update the “extend srf” command works intermittently. In a SR suddenly the “out” extension no longer works, or it extends up to a certain point, or it does not cut the surface with the merge option. It’s a continuous disaster!
Is it possible that this command cannot work well? I test it from version to version, from SR to SR and I always find problems.
For example, in the latest version of Rhino 8 you cannot extend beyond the edge, but only works towards the inside of the surface.

We had this on the list as RH-83755 ExtendSrf: Failure cases
This is fixed in 8.13.

Not to be argumentative… this bug will be fixed in the next SR, but surely something else will not work well. Since the early days of Rhino 7 I test this command, and I always find that something never works as it should. Every SR is a surprise (in a negative way).

If we did this with every command present it would be the end for any CAD. The bug can appear, it is part of the complex development of a software, but not in fits and starts, one version yes and two no, etc.
In my humble opinion, for a Nurbs modeler, the surface creation and editing commands should work flawlessly, and not imprecisely or piecemeal.

@davide76 prophecy came true!

1- Open the attached file

2- Run the ExtendSrf on this edge.

The crash bug is indeed fixed in 8.14, as it was found a couple of weeks ago.
We still have a lock up bug on the list with ExtendSrf, which hopefully gets addressed soon as well.
@davide76 if you have cases you run into that don’t work it is always helpful to send them in.
