Problem choosing map in OS X

Unfortunately swing does not work properly in OS X. To solve this problem, you need to specify the map in a config file. To achieve this run the following command to generate a config file:

java -jar FlowsGameServer-v1.0.jar —generate-config=game.conf

next set the Map field in the config file to absolute address of the map file then run the server with following command:

java -jar FlowGameServer-v1.0.jar --config=game.conf
