I found a problem in the work of the PCС2ng program.
In the last turn of my game I had one fight. When I press the "V" key, a battle window opens where the parties involved in the battle are described. When I want to preview the fight and press the "Play" button, the program closes unexpectedly without any message. This error occur as on my local game as on my game data on PlanetsCentral site.
