mission crash in Bloody Sky of Karella
 

Hello, i have experienced a crash while playing Il2 1946 4.13.4.
While looking around the pilot career section, i came across Bloody Sky of Karella, the SB-2 mission to be exact. After completing the training mission, the first proper mission appeared, drop cargo in a certain area. After clicking the fly button, the game begins to load and an error appears on the screen. Mission Loading Failed: null. After looking at it closely, the cargo has flares written in brackets, but the aircraft loadouts do not have neither cargo, nor flares in the loadout tab. I am very curious as to why this error has appeared, as the loadout should be there (aircraft is a stock one), however the mission continues to crash. Could someone please help me figure out what is going on with the game.
