[GAMEPLAY] Illoi bug?

sooo I in game against an illoi where i encountered, what i believe to be, a bug.

In the game me, the jinx, and my support sona were in lane doing fine in the early game. when all of the sudden the game started to have frequent frame drops. It became worse when illoi got her ult ans when she used it, my game would freeze on the frame she ulted. I can tell that it froze because the sound was locked also to whet was happening in that exact frame.

in the link was the match if you reviewed the kill record it was usually around where me an sona died together.

in terms of recreating you can try a illoi without a skin, DJ sona, pool party graves, and skinless jinx. as for the masteries they are listed in the match history attached
