Urgot's Unlimited Purge
[Gameplay] Soraka can give Urgot Unlimited W - Purge
When playing as Urgot with an allied Soraka, being healed with W - Astral Infusion causes Urgot's W - Purge to be active until manually shut off or upon Urgot's death. I have only encountered the bug once but the ability seemed to work as intended until I received a heal from W - Astral Infusion. It became very apparent after reviewing the replay that, which I have linked below. Even after dying and respawning, activating W - Purge continues to stay active. The bug appears to last throughout the entirety of the game after being affected by W - Astral Infusion.
I have no history of game design or programming but at first glance it seems that the adjust to W - Astral Infusion is a possible catalyst and may be worth looking into. Below I have two clips from the game where I encountered the bug. The first video begins a few seconds just before the bug-causing heal and the duration of the video I feel showcases the nature of the bug. The second video below showcases that the bug does not cease to end postmortem.
