Some systems called mixed-member proportional systems (MMP), like the ones used for electing the national parliament New Zealand, at least partially compensate for overhang seats as well, by adding back that many seats to the assembly if needed, but this is not a perfect correction for the disproportionality. In Germany formerly even more seats were adding to the Bundestag, to get fully proportional results, but as per the latest reform, parties simply may not keep overhang seats, meaning they might not be able to keep all constituency seats they "won" in.
