Me and a friend played this,every pirate or enemy we encountered had no weapons
making it no fun to fight "enemies" that wont even dmg your ship :c
Most probably you have started your playthrough on an older version, and then upgraded to a0.8.11.
Then you copied the database folder from the old version into the latest one.
This would cause all random enemy ship generations to fail and result in all enemies having no weapons no shields and missing other different systems.
Also if you run the server with console, then in the console you can see if there are any errors.
Please try restarting the run, and keep an eye out for the console.
If you notice any error messages - please post them here.
