The erroneous polygon was in the process of being corrected by me together with a team of OSM cartographer members from Romania. With your changeset rollback, streets and sidewalks created in that changeset were lost. Ask before you do something stupid like this. I see that you edit chaotically everywhere on the planet, I don't understand this maniacal rush to edit places you don't even know. You reversed and abandoned the lost information without even bothering to mark it back. Btw, not even with your reverse movement, the polygon is correct. If you want to do something good, go and modify only the polygon of the forest node by node, do not revert the changeset full of data
