I couldn’t find the way how to create those garages in game except Config ones. Secondly, I tried to give car to myself and saved in Pillbox Hill Garage. But wasent able to store my own car in other garages need to know about that part. Third, The Shared garage system works properly As I am using Police garage is shared garage for job of PD , Even not able to store it in garage
to create garages is the /mgarage command.
The code that is on gitHub is working fine, however these days I will upload a big update with new things and many improvements
