did you also install the included TalkingNpcVehicles.cs file assuming not?
docs show.
1. Spawn the vendor
/talking_npc vehicle copter <"Unique_Vendor_Name"> <false/true>
2. Create vehicle spawn points for copters
A message will popup explaining how to add the spawn points.
if nothing popping up most likely means TalkingNpcVehicles is not
loaded let me know.
Nothing inadequate about that.
if you would like contact Lizard Mods#0947 on discord hes been working on a video for me. as there is 100000000 of posabilities.
