Strange building bug in JOSM

1

I don't know if this is the right place to report it but anyway...

I have encountered this bug several times. It happens when I combine several building segments into one. Suddenly one or more of the ways flies away in one of the directions of the building.

Screenshots: Before combining:Before combining Before combining, zoomed in:Before combining, zoomed in After combining ( :O ):After combining After combining, zoomed in:After combining, zoomed in

What causes this bug, and how can I avoid it? I'm using the building tools plugin, and usually draw the seperate parts of the building with one of the marked so it follows the same angle. From what I have collected, it might have to do with some node going a bit out of the completed polygon, if that makes sense. The bug seems crazy anyway though...

PS: Made a bug request myself as well: bug

I think the JOSM "combine" feature works fine only when polygons are strictly adjacent, mean not overlapping or nodes not joined to the nearest way. More than a screenshot, your bug report should provide an XML file ('save as' in JOSM) of the building blocks you want to combine (e.g. copy them to a new layout and save). This will be used as a test dataset for the developers.
