Hi dada24

I would like to point out two things that keep reoccurring in your edits in Budva.

First, you delete outlines of buildings and replace them with new 3D versions. As i already said in other comment, by doing this, we are losing history and there is high chance to lose details. Like in the case where you have deleted old building https://www.openstreetmap.org/way/183678986
, replaced it with the new one and you haven't added the school tags that previously existed. Now the new version is only tagged as building and we lost detail that it's actually a school. The best practice is to preserve old outline and reshape it as needed, it can be tedious but please delete elements only as last resort. In this case there was no reason for deletion

Second thing, you keep using "buildingpart" tag which is wrong! it should be "building:part", you omit ":" for some reason so please pay attention to that. As it can be seen in this changeset: https://www.openstreetmap.org/changeset/162599385

If you have any further questions feel free to reach out here or via private message.

Best regards
