I was working on wards boundaries of that administrative region, so I might have accidentally broken the boundaries. You can assist by fixing the geometry relation.
I am also trying to figure out the broken issue.

Serious issue !!! An entire forest has been converted into farmland. Please undo your changes.

Wrong mapping. Non existing farmland has been traced inside a forest. Please delete it.

Wrong Mapping!!!! You have mapped a huge part of already mapped forest as a farmland. Please delete the wrong farmland.

Yes, I know, that's my responsibility. I always correct my mistakes myself once I know about them. I just mentioned you to correct them as you were in the process of correction. If you don't want to, leave them, I will correct them.

I checked out the points. The tagging were mixed up as mapping was done using JOSM. In JOSM, those tags were not rendered so it got mixed up. It was not intentional. Thanks for flagging. Please you can make corrections.

Wrong mapping. Rocks were mapped as houses.

Duplicated landuse. You have mapped woods inside woods

Hello Devraj, you have created a lot of duplicated buildings. Please delete them.
Always remember while mapping in JOSM, you are not allowed to map in the hatched region.

Wrong tagging of road. A motorway is not the one in which motorcycle or motorcar can run, a motorway is a very high-speed road. Actually, there are no motorways in Nepal.
Please read this wiki to understand more about highway tagging and do map accordingly.

It is correct. I have used "name:ne" not "name:en". (ne = Nepali name)

CORRECTED TAGGING, replaced 'Title' by 'name'.
