It happens to me all the time and its very very annyoing. You get warped back from one to another until you cancel all +size nanos and then get killed by opponent with 1 HP and unbuffed.. just great. It usually happens when you zone from A/B/C to mid.
It also happens when you want to go to A/B/C I always get warped back and then have to run instead of using teleporter. That sux so much.

Plz fix that asap!!
