Hi NeisBot, 

Yes, that's intentional. Don't worry. I'm a geomatics engineer for the City of Lachute. I've prepared all my layers with tags to update our area.

That said, I tried to find a way to delete everything at once, for example, the landuses, but it's really complicated with the nodes, paths, and relationships. Do you have any suggestions? That way I can quickly delete and then upload the new layers.

Greetings
