make 2 colshapes around quarry (like a turf box) and if you exit the inner one in dumper it gives a message saying "you cant take this vehicle out of the quarry, turn back now" and when you exit the outer one the engine turns off and cant be started.
+1 and it would be great if gold miners use bulldozers for this job cuz most of the gold miners use bulldozers in real life.so it would be great spawning a bulldozer near job marker and take bulldozer down of the quarry and there will be one marker.stand in the marker and the message will show to deliver these goods to one destination.but add ghost mode when doing gold miner job when in the quarry cuz some will abuse it like crashing the civilians wantedly.hope u add this too.
The problem isn't that criminals will troll them, but they can troll criminals with their Dumper, since it's a big vehicle and can destroy cars.
