eXtruder misbehaviour

[skyper]

There was a ​bug reported on the German mailing list and I just found another misbehaviour. All I use is the extruder mode (I gonna attach the example .osm file​):

Misbehaviour (upper samples)

1. Draw way a
2. Add node A
3. Draw way b (ALT)
4. Move northern wall of way b

Instead of moving node A a new node is created which is only part of way b.

Bug (lower sample)

1. Draw way a
2. Draw way b (ALT)
3. Move northern and/or southern wall of way a

Nodes A and B should not be part of way a anymore but they still are. And the new corner nodes of way a are not added to way b.
