3. Fixed sounds, some sounds were not played;
   
4. Fixed star systems hit boxes on the map view;
   
5. Building ships for agents away from their shipyard is not possible anymore (https://discord.com/channels/664757869404618753/699258028523782194/817309693947936848);
   
6. Fixed the unread messages counter;

Misc

1. Slight increase of the maximum jump distance on the map (should allow for less linear maps);
   
2. Global balance update of the ships;
   
3. Sounds that are replayed start from the beginning rather than adding up (for instance when queueing many buildings at once);
   
4. Icon modifications:
   
   1. Ships icons not visible because of low visibility,
      
   2. Icon for lex validation.
