TypeError: Cannot read property 'get_Map' of null

I had same bug today in 1 vs 1. Errors:

Error: Uncaught TypeError: Cannot read property 'get_Map' of null, Script: http://atwar-game.com/java/atwar.core.min_v13.js, Line: 158, Column: 395, StackTrace: TypeError: Cannot read property 'get_Map' of null

Error: Uncaught [object Object], Script: http://atwar-game.com/java/atwar.core.min_v13.js, Line: 158, Column: 395, StackTrace: [object Object]

Sceenshots: http://prntscr.com/dbm90y and http://prntscr.com/dbm7v7

Edit: Bug started after one of my units was unselectable because I was moving it when turn ended.
