GTA5 online weird glitch #2 (Diamonds are for Trevor)

So, I had already taken out Merryweather and got the diamonds. Once in the boat I knew to expect 2 boats and a chopper to come after me. The boats came but the chopper was not moving.... Just watch. LOL GRAND THEFT AUTO V https://store.playstation.com/#!/en-us/tid=CUSA00419_00
