Hi Abetsi,
In your recent changeset 155158046, you left a large hole in the map. See the east side of this changeset.

This area is mostly forest but your changes have broken the multipolygon that was there.

Can you fix this? Please make sure after editing that you have not broken multipolygons. You can just reload the map at a high zoom level to check everything is fine.

Best,
Alk
