You recreated multipolygons around Ivana kapi, aroudn Ziedoņdārzs and in areas south of Daugavas Stadions. The only useful changes done by you are at the third location. 

What was the reason for it? They have no reason to exist! These elements can exist as simple polygons without problems! 

I understand it might be easier to create areas which connect to each other using the multipolygon method. But I don't see a reason to restore multipolygons if you are not going to change anything there or if you're going to just move a few nodes around!

Fixing this edit without reverting your good edits seems very hard if not impossible. I might have to revert the entire change set if I'm not able to find a reliable way to fix this.
