This is making him borderline unplayable right now and I didn't see it getting fixed with the 5.18 patch. Here is sirhcez getting the same bug that I have been getting quite often (at the 20 second mark.)

YEAAAAAAAAAAA!
frigginmurlocs9 votesWe can once again Q without QQing, 
mains unite
EDIT: you'd think something that important would be in the patch notes
RiotvLemon3 votesYes, it should have been in the patch notes. The fact that is not there is my bad, I didn't think about adding it till yesterday which is too late.
Sorry about that (and the bug all together) :(
frigginmurlocs1 votesIt's fine I understand that there is only so much room in patch notes and this is the worlds patch
Fatespiker1 votesStill bugging for me.
hxcbrown1 votesAre you guys aware of and/or working on the failed to log in bug
s1rjack166 votesmade me lose my lane in ranked :/

A better question is how did you ever consistently win lane against anyone besides 
lol
Yuri By Mail2 votesIf susaN can really make it to the first recall without dying they do start getting the advantage late-game IMO. I'd consider it a won lane for susaN if they can manage to just not die and keep top in, well, the top lane.
anonymous11113 votesNasus is one of my favorite go to counter picks in top lane, but he is straight up unplayable with this bug. Hopefully bump/up vote until we find out if it was fixed in the patch and not documented.
tr8terburns3 votesThe worst part is when 
appears out of nowhere and you get rooted for a good 3 seconds trying to Q the right one :c
GimmeYoPeaches2 votesBump every hour, on the hour, until bug is addressed/fixed
Smalltoejoe2 votesMultiple people have posted this complaint and Rito has still overlooked it. Come on Rito. Come on.
LegendmakerGX2 votesYou know.....Riven is more important...... Really question how bad Riot team are at fixing stuff now. Usually a bug takes like 3 hours in the past to fix....NOW its 1/1.5 weeks to even fix the champion or people start making rage threads to riot about how they are not even getting the job done. I don't get how Riot didn't disable Nasus too like they just did to riven right now, probably will take then 3 weeks to fix both champion I guess so they had to ALL focus on 1 at a time.
DokiDokiTodoroki2 votesSome bugs are easier to fix than others. But sure bring up a completely unrelated champion because more QQ.
LegendmakerGX1 votes.....Really? a slow animation buff for Nasus is a hard bug to fix? Riven is sort of related why? they disable her but not Nasus for people who didn't realize his bug is not even fixed. Which this bug is game change for nasus.
choonk2 votesonce I was against nasus and he was like SLOW MOTION CANE
Fatespiker2 votesI was told it would be fixed in 5.18. Started ranked game. died to a Darius because it bugged while i was dueling and started steamroll exacerbated by the bug. Seriously wtf, if you say something do it. Not doing it and not mentioning that fact loses a lot of respect in my book. Especially when it has ranked consequences.
Guy Fox Teemo1 votesWhats the bug? I seem to be doing perfectly fine with him. Although I use the Legendary Skin, Infernal Nasus idk, if it's only his base skin.
PapaGreg211 votesGo to about the 20 second mark. This happened to me (with the same skin) about 30 times in a ranked game. It was horrible.
Sinister Mars1 votesHappened to me! A ton.
SkinnyDots1 votesOMG WHY DONT I GET CREIDET I HATE HOW U FIND A BUG AND NO ONE CARES OR FINDS OUT BECAUSE U R NOT FAMOUS LIEK HIM 
Kat Head1 votesTy Skinnydots for finding and directly leading to a timely repair of the Lag Kane.
