Lux Finales Funkeln bug

Today (19oct) and yesterday (18oct) (2 games) Finales Funkeln missed, even when I got the target centered in the red pre-laser line. Has anyone experienced the same? I dont know what exactly causes the bug. but in yesterdays game, yi was standing behind their mid turret and I missed and today tristana was standing behind our mid turret and I missed while I had them both centered in the red line
