Ok. I'm Romanian, don't know bulgarian. From OSM Inspector I saw the missing border members segments. As I understand you are importing data, but try to work with it step by step.
In JOSM add the plugin https://josm.openstreetmap.de/wiki/Help/Plugin/UtilsPlugin2
to be able to use Replace Geometry tool. It's useful for realigning current ways with new ways(new geometry). Good luck.

Something went wrong with your edits. Many relations broken and unclosed near the border with Romania.
I'm trying to fix them.
Be more careful next time.

Hello. Why are there two parallel boundaries admin_level 6 ? If it's correct then fix this ring not closed error for 2959529.

Eu nu m-as lua dupa placute. Mergi cu streetview pana la Bld. Dacia si vei vedea 3 variante. Cred ca Scoala tine de Strada Castanilor care ar fi de fapt in "spatele" scolii, posibil candva se lega de Aleea 1 Castanilor prin curtea scolii. Dar toate celelalte blocuri pana la Bld. Dacia au adresa Aleea 1 Castanilor.
Asa apar si pe liste la sectiile de votare.

Salut. Esti sigur ?

Golenti - Poiana Mare currently it is not usable. The road is paved over the track near Poiana Mare train station.

Check again what you edit!!! Now part of Danube is not rendering because you split ways around the island. Also the island is not rendering. Please fix this or we revert all the changes.

Dude, you did it again... Deleted nodes/ways part of a bigger multipolygon that represents farmland. Click and see those incomplete lines relation/4711450#map=12/45.0979/27.3761.
Also see above those warnings at the details of your changeset.
All of that can be avoided with JOSM.
We will have to revert again your data.
By reverting, your work is all for nothing if you don't edit carefully.

Hello, you broke some ways in the landuse relation for farmland. relation/4711450
Browser editor is not good for relations editing.
Please use JOSM for better control. Some of your edits might be reverted.

Hello. Braila what ? Give more detailed description to what the edits are about. Your last week edits broke some ways. The landuses are not rendered anymore. Please use JOSM for more control over relations and big areas.

Hello. It's not missing. There is no platform to stop here. It's on the other side of the intersection for the direction Depoul Alexandria -> Piata Unirii.
node/2521568625.
Appreciate the help, but browser editor is not good for editing relations, especially public transport. Please use JOSM because it has built-in validators. Thank you.

Salut. Mare rugaminte, daca vrei sa editezi relatii de transport public foloseste editorul JOSM(E mai greu de invatat la inceput, dar ofera multe functionalitati). Altfel se strica ordinea in relatie a statiilor si cailor si nu mai ruteaza corect in aplicatii. In ultimele luni am folosit OSMInspector pentru verificarea relatiilor si am reusit aproape 95% din relatii sa le corectez(apar verzi pe harta). Acum apar din nou negre(diferite erori).
Multumesc.

Salut, incerc sa inteleg de ce ai modifica parcurile in zone de padure cand ele sunt clar parcuri ? Plus campusul universitatii si spitalul de neuro care clar nu sunt paduri...
Vezi pe wiki diferentele intre park, wood si forest.
leisure=park
natural=wood
landuse=forest
O sa dau revert la aceste modificari.

Salut, ti-am modificat eu tagurile. Drumul nu e construit peste noapte. E doar o propunere asa ca trebuie sa fie marcat corespunzator ca proposed, apoi cand incepe constructia lui va fi in construction si la final va aparea ca celelalte drumuri.

Salut, de ce a fost sters acel segment ? Cum ruteaza virajul la stanga ?

Salut, ai dublat tagul status. Apare status status=AC. Nu apare bine pe harta de infrastructura.

Dude, you deleted a farmland multipolygon. This change set will be undone.
1303549, v27

Sorry, not understanding what is the meaning of this edit. The road is gone now, and routing is bad. Trying to fix this.

Salut, mai mare atentie pe viitor, in zona Magnolia ai sters un segment care tine de o relatie multipolygon. Pot aparea probleme de randare pe harta. Nu sterge fara sa fii sigur ce se sterge. Mersi.

Hello, thanks for that. I noticed it too. I made the changes in Osmose. The recommendations were incomplete. Will make the changes soon.
