How to reproduce:
# Buy a shop module
# Create a Faction (I chose "RandomName" as name)
# Create a Space Station (I chose "RandomStation" as name)
# Add the shop module and you as owner
# Set to allies only or faction only
# Sell something (for example one of the 30 hulls given on start or all salvage modules)
# See the error message "Server: No permission to use shop"
Permissions (allies and faction only) do not allow you to use it if you are an astronaut. Not even in a ship containing a faction-set faction module you can use shops set to allies or faction only.
It should pop up a warning message to inform about the 'unfactioned' shop now checking for
"Allies Only" or
"Faction Only"
obviously not working at all.
