You are not wrong. A hotfix entered LoL at night to fix this bug

Riot is releasing a patch for official servers.

Riot Games informed the community about a small patch that has been introduced to the official League of Legends servers tonight. While the changes aren’t big, they will certainly help some players.

Namely, it is about the popular Nautilus, whose skills did not work properly.

Hotfix during the night

Three days ago, on May 26, the official update 11.11 was released on the official League of Legends servers. It turned out, however, that there was a bug in it that prevented Nautilus from working properly.

Namely, it is about slowing down on E:

  • The slowdown value: 30 / 35 / 40 / 45 / 50%

It wasn’t stacking properly and is now fixed in today’s hotfix.

But that’s not all. The AP factor on champion’s W has also been improved. As reported by Rioter Mark Yetter, the changes have been on the official servers for several hours.
