This week the following was bug fix:

• Corrected trade errors.
• A disconnected timer was added in the absence of communication with the server for more than 20 seconds. The game will not last anymore if the connection is broken.
• Enterprise upgrade shows the price.
• The color change is eliminated at an accidental click when creating a server on a color line in waiting menu.

Not yet fixed:
The timer does not restore the time to 30 at different actions of the player. It may be necessary to re-write the timer work. Also, when the player reconnects to the server, the server crashes. Correction of these errors will be completed next week.

I also began to study the documentation of the SFML library about introducing sounds into the game. At first glance this is not so difficult.
