Ship is spinning out of control all of a sudden

[NoahThomas29]

so im at a loss as to what is going on, i have been doing refueling mission on minmus. and now after undocking my refueler using the grabbing unit from my ship, the refueler now spins out of control any time i throttle. this doesn't make sense cause this is out of no where, i have been doing this for a while and everything has been fine until now. please need help!

After you do that, is your thrust vector aligned with your center of mass?

Ok im stupid. I checked my fuel tanks and they had uneven amounts of fuel, I transferred the fuel between the tanks and now the ship is working properly again. Thanks HebaruSan for the reply.
