10838	"on incomplete relation: ""combine way"" deletes all ways"	malenki	team	"How to reproduce:
* get a relation with at least three connected ways (no difference if these are connected inner or outer ways of a multipolygon or a route. For testing purposes a route would be the easier choice)
* download two of these ways belonging to the relation
* right click the route relation in the relation window and ""Select members""
* apply the Tool —> ""Combine Way""
Result: all selected ways disappear, their nodes remain (JOSM reports the ways as deleted)

expected result: A warning that not all selected ways can be combined since they are not downloaded

Sure, it is a stupid thing trying to combine not-downloaded ways but since this happened to me today by chance I'd assume I am not the only one to whom this error may happen.
I tested back to r6210 for this behaviour which showed there, too.

Maybe this issue is related to #8082?"	defect	closed	major	17.07	Core		fixed	relation, incomplete, combine way
