So a few games ive been noticing that my eternum Rek'Sai has been acting strange because stun durations have been lasting longer than they appear its happened almost every game when i got stunned by a udyr i couldnt w nor could i w into e for 10 sec when i got stunned by an annie i tried to w again but still nothing i looked at my ping and i wasnt lagging so i think there is a bug thats making stun durations last longer than they are supposed to 
I've only had personal experience with the bug where your tunnel will successfully form, but you'll be left on the same side of the wall.
i've never had this problem using eternum rek'sai
I second this motion, only as normal Rek'Sai. Sometimes I just randomly stop moving as I click onto a tunnel I know has refreshed already. I'll be clicking on it rapidly [as most players do to move, especially in tense situations] and then I'll randomly be unable to move, cast abilities, or attack. After stuns wear off it is the same effect, no ability to move, cast abilities, or attack. Now, I've noticed that this only happens when I'm burrowed.
This happen to me once when I was trying to juggle an Amumu for some reason I just stoped and wouldn't move for a longer than normal duration I couldn't recall if I had been q'd by Amum but I know for sure that he didn't ult me at the time even then the time his q stun should have worn of on me and the time I was sitting there under him as he walked about was abnormally long.
