A-Chassis Breaking on Vehicle

Hello,
I have a chassis but it doesn’t work every so-often. I don’t know why but I get the Error.

Network Ownership API cannot be called on Anchored parts or parts welded to Anchored parts.   Server - Initialize:611
 20:07:39.196  Stack Begin  -  Studio
 20:07:39.196  Script 'Workspace.ALP.ALP.A-Chassis Tune.Initialize', Line 611

Can anyone fix it?
