Yasuo zapped by spawn laser if he ults near safe zone at bottom of stairs

SUMMONERS RIFT YASUO

In enemy base, try ulting at the foot of the spawn area. The height of the ult mistakingly judges Yasuo as on the stairs and kills him.

I haven't tried it, but I'd imagine ulting enemies at the base of your own stairs might just zap them too. Seems to be a miscalculation in how the engine determines if you are on the stairs. Visually it seems like Yasuo is, but his shadow and place he dies is clearly NOT in the zap zone.
