Hi! Thanks for notice. I'm just starting here, step by step, but I definitely didn't expect such a small limit of unsaved changes in edit mode. So I had to make this intermediate set of edits to continue my unfinished work. There are many places in the city that have been seriously rebuilt in recent years, and this is not reflected on the map, so I want to show them in as much detail as possible. I understand that this data can be important for building routes for various categories of citizens and transport, so I will do it as carefully as I can.
