[GAMEPLAY] Shaco's Q, permanently invisible

I just played a ranked game as Shaco jungle, everything was normal until around 15 minutes in after I used Q I never came out of stealth. I didn't realize it at first because I was doing a jungle camp but noticed that the jungle monsters didn't attack me and were acting strange. I decided to walk to bot lane and stand next to enemy champions to see if they could see me and they didn't react (post game chat confirmed they couldn't see me at this point). This lead to an extremely unfair advantage as I was able to walk around the map just auto attacking anyone I saw and they could do little but run around, use Zhonya's and flash away hoping to escape me (admittedly this was hilarious, until I felt bad and realized it was an extremely unfair advantage). They said all that they could see was my Ravenous Hydra procing on my auto attacks. They used pink wards and upgraded red trinkets to "see" me. They said that I was transparent similar to how a stealthed champion looks under an enemy tower. After I died the first time after the bug occurred, from my point of view, I looked invisible still but the enemy team could now see me. Whenever I try to press Q (before and after my death) it said "Cannot use this spell yet" as if it was on CD but it was grayed out and unclickable. I don't have in game footage and forgot to take a picture of it. I hope this provides enough information for someone to look into the bug to fix it. I could understand how the enemy team felt and they were accusing me of hacking, which I was not doing.
