10268	Joining of overlapping polygons results in multipolygon	tumsi	tumsi	"> What steps will reproduce the problem?
1) Draw two or more overlapping polygons (they do not need to share any nodes but it does not make any difference) and select them
2) Use tool ""Join overlapping Areas""
> What is the expected result?
As in former versions: The polygons are joined according to an OR-function. This means: every part of the polygons, which is overlapping with the others or only belongs to one of both, goes to the merged polygon. If there are areas enclosed by and covered by neither, the new polygon is turned into the outer part of an multipolygon.
> What happens instead?
Now also two simple overlapping polygons are converted into multipolygons like a XOR-function.
