One of those bleeped up vehicle spawns again

[Rien]

I was flying around in my hydra a few minutes ago, when I suddenly had a big fps drop, I checked my radar and noticed a lot of vehicles in one spot, as I went to land closer to take a screenshot, I hit a stupid tree top and died :<

Fortunatly, I managed to get back to the crime scene, and still managed to take a pic of the location
