Teemo Shroom Timers (Howling Abyss) (GAMEPLAY)

I have noticed in ARAM for certain, while using Omega Squad skin that Teemo's Shrooms show 300 at all times on their timer. This does not decay or drop throughout the game yet the shrooms still disappear after the allowed time limit. It isn't a serious issue as 5 minutes on Howling Abyss is a long time and especially when his shrooms are easily triggered or removed. Just thought Riot would like to know. I have not tested it on other maps or his other skins but this is the information I have. Hope it helps, at the very least it isn't too significant if it is limited to Howling Abyss.
