Nautillus and Yasuo ult interaction gameplay bug!
I was playing a ranked game as jungle Nautillus yesterday, and a really strange interaction occurred twice. The first time I noticed it was during a teamfight. I used my Q and then ultimate back to back on the enemy Tryndamere, and Yasuo ulted off my q. What happened was the enemy Tryndamere was then suspended in the air for several seconds. This happened again another time, during the same game. So I think the way to recreate this is to simply Q on Nautillus and then Ult right away, with no delay in between, and have yasuo ult off the Q.
