A lot of time has gone into making the mod much, much more flexible for server owners/admins. Everything from disabling specific turrets, mod recipe usage, turret volume and global targeting parameters can be customized to the server's needs. Check out the new configuration file for details. We strongly suggest you remake your config, aka deleting the old one, start client/server once and then change the new file or else you will have obsolete entries that do not work in it.
