Current questions and answers regarding the map editor.

Hello. I've encountered an unpleasant problem. First, the editor crashed while I was working on a map. After the next attempt to open any map in the editor, nothing is displayed in the right column. The problem turned out to be that a lot of XML documents have disappeared from the Editor folder. And here's the question: is it easier to reinstall the game to solve this problem, or is it enough to find the missing documents somewhere and add them to the folder?
