Jinx Ult is invisible

While I haven't played another game since (it really was about half an hour ago), when we played against a Jinx in a Normals on SR, her Ult rocket would not have any textures, only sounds and fire from the end.

I can try to replicate this later, but atm I am in no shape to play again. If anyone fights a Jinx, let me know if you encounter this problem (Me and 4 other friends were in the same game and noticed this)
