3728	"""undo"" does stupid things destroying data"	Cobra	team	"When undoing changes to ways, josm sometimes behaves really strange. All problems seem to be related to segments, as far as I could figure out.

- some ways (newly created, so no damage/change to existing osm data - I hope so) disappeared forever when I used ""undo"", only the nodes still existed. ""Redo"" didn't bring it back. This problem occured another time with the a new way using the surviving nodes. Another way created like these ones wasn't damaged when undoing.
- segments of a few other ways were ""sucked"" to a node belonging to another way - some segments were connected to this node (of a newly created way unrelated to the undone changes) instead of their old nodes which were left without a way on their position.

I couldn't reproduce these problems for sure, but they did appear quite often, it seems they occur randomly."	defect	closed	blocker		Core	latest	fixed		nakor.wp@…
