Summary of the bug : With correct timing it is possible to lay mines in the Air
Which version of Grip were you using :
When does this happen : When laying a mine just before your car goes of the track
On which track did it happen : Yuri Industrial/Wastes
On which speed did that happen (if related to physics) : Normal/Wild
How often does this happen : Always if you time it correct
How to replicate the steps (if reproducible) :
After getting a mine use right before your car lifts off at a jump like U-Turn exit or the split path on Yuri
if done correct the Mine will float in mid-air a few meters away from the tunnel exit.
More details :
I've been able to it on every jump on Yuri and some places in Wastes on Normal and Wild speed.
Mines become unavoidable. Doesnt seem to work when you drive on a ceiling as the mine will stick to the tunnel exit.
Your specs :
Intel Core i5-2500k
