Last Roman COOP bugs (Desync CTD during river crossing battle and siege lags)

Last version of the game. Both players has Russian localisation. Last Roman camping COOP.
1) Every time when we try to play battle as defender against river crossing AI we have CTD. Error says something that Administrator left the game.

2) During siege battle as defender when you try to change formation of unit (via RMB) there is a huge freeze if you move mouse cursor to blocked location.
