[GAMEPLAY] Rek Sai tunnel doesn't work after being devoured by Tahm kench

In a game I was playing with friends one of my friends ( ) on voice chat became frustrated when they couldn't tunnel properly in team fights after I ( ) Devoured them. After Devouring Rek'sai (While burrowed) when immediately casting tunnel after Tahm Kench spits her out produced the tunnel but did not move Rek'Sai from the spot she was spit out. It continued throughout the game causing my friend a lot of frustration.

How to reproduce this bug.

Step 1: As Tahm Kench devour a burrowed Rek'sai Step 2: Allow devour to time out or manually recast the skill Step 3: As Rek'Sai immediately cast tunnel in any direction

Result: The ability will be put on cool down the Tunnel will appear on the map, but Rek'sai will remain in the spot where Tahm Kench spit her out.

I will update this if I find out any more about this bug because I am not sure but I think I remember Devouring Rek'sai when she was unburrowed and she still cast tunnel immediately after being spit out.
