Well, your description at first sounds like several problems at the same time.
1)
None of the turret I connect appear (they were vanilla BUT quality laser turrets)
That's intended as laser turrets are not consuming ammunition. Currently only ammo-turrets (e.g. gun turrets or rocket turrets) are supported, neither are electric-turrets (like the laser turrets) nor are artillery-turrets.
2)
nor did the radars appear on the controller
Quite surprising. Are you sure that you really placed dart-radars on your platform - and not conventional radars? 😉
3)
I agree with you, that such a crash shouldn't happen. If you could share your save file with that the error occurs, that would help me a lot to narrow the problem and to fix it.
