Zilean and Kindred R bug

What happened: I ulted myself with Chronoshift (Zilean) because I got hit by Death Sentence (Thresh) and while I was reviving Lamb's Respite (Kindred) was used where I was reviving. This resulted in me (Zilean) reviving with just the bare minimum of 10% health (less than 300 health) instead of about 1700 health (1100+2*300 AP).0
