[GAMEPLAY] Rek'Sai Tunnel Glitch

I found a bug with Rek'Sai's Tunnels that caused one to stay on the field indefinitely. This Tunnel could be Ulted to and freely used. It didn't count towards my Tunnel counter on my ability bar.

While I do not know how to replicate it, the mere fact that it exists is a major problem as if exploitable, it could give Rek'Sai players an extremely unfair advantage. (Making Infinite undying Tunnels if the bug truly disconnects the glitched tunnel from the counter).

Here is a picture that showed the glitched Tunnel. The cooldown bar is completely black yet it does not disappear. You can also see 2 other active tunnels on the field (both in my base, one over our nexus and the other near the top) yet my Tunnel counter only lists these 2.
