This should be fixed in the latest update

What exactly cause that ?

Seem like happening after a buffing Depot with petrolium.
To split the course in half.

Is that even possible to drop a buffer of petrolium to refill my regular depot ?

Yea, i had made a mistake with buffer depots and fluids. Its fixed now
