Those do not work well with the connector, it is still there after copy paste or redo, but the signal is not connected to the others radar. No error or crash, it's ok.
I tried using Picker dollies mod too , it worked well as the radar can be moved and the connector follows and stay attached for signal broadcast, it continue working.
The redo/copy is also problematic when there is no Picker dollies.
Anyway thanks for the quick work !
