Damage over time, on a enemy champ.
then you are dead, make it so you cant refund the item u just buyed.
i dont know why this has not been fixed yet, so here we go again with the same report like last time
then u play a champ, that has a damage over time skill/basic attack.
and you are in fight and dies, but have put a damage over time on your enemy team.
if you now buy a item, then it can't be refunded.
the system think you are still in the fight, but you are dead waiting to respawn
(twitch, teemo, daruis, i test it on them and the bug is working 100% on them)
hope dev or other members see this so it can be fix.
still waiting for this to get fix way back in S4.
p.s. sry for bad english.
