Backup services not leaving

What FivePD version? 1.1

What issue are you experiencing? When calling for backup services, specifically Air Ambulance and Tow truck, the services wont leave when they are done. The vehicle will also bug out and not be able to be moved by the player or AI. If the player jumps in it and tries to delete it, nothing happens either. 

Please explain in detail what you're doing for this to occur Not much really, i call for backup and they come as they should. In the air ambulances case, sometimes when the message "No landing spots" comes up they land either way then bug out, and if they dont land, they will just hover over the ground at like 30ft. If they land and do what they should, they will turn on the engine but never takeoff. In a few cases they have hovered 1ft over the ground and slowly gone forward, but never left the scene. In the towtrucks case, sometimes when it picks up cars it will bug out before being able to drive. 

Attach here a screenshot of your console (F8) Will provide next time i experience either of the bugs, as i forgot to screenshot it last time.

If you have any, please provide video, picture, or GIF of the error you are experiencing:

------- FOR SERVER OWNERS ONLY (FILL THIS OUT IF YOU'RE A SERVER OWNER / DEVELOPER) -------

What OS (Operating System) are you using (Ex. Linux, Windows)? Linux

What version of FiveM are you using? 18.6.8

Are you using any other server side/client side mods? If so please list: We use a lot of different scripts, but nothing has ever affected the towtruck before. It worked pre 1.1 like it should. We do however use custom models on all the services.
