Tahm Kench Devour preventing proper movement commands [GAMEPLAY]

In my last game, I was flash + devoured by an enemy redside Tahm Kench just outside the space in between his inner and outer turrets. When he spat me out and I began clicking to move away, I instead moved further towards his inner tower despite clicking in the nearby bush in redside jungle. It took about a second for my movement to change direction away from tower range, by which time I had taken one tower shot and the next one killed me.
