Reksai Tunnel Bug

I was playing Reksai yesterday and I placed a tunnel to go through the botlane tribrush big terrain. And it made the tunnel all the way through. But it just sat me there, not letting me go through and essentially animation locking me for about 3/4's to a full second because it's how long it would have taken to make it through. And then later in the same game I tried passing through a spot I do all of the time, I made it half way through the terrain and then it rubber-banded me back like it was CoD MW2 with 2k ping. Except I wasn't lagging at all. I've never seen or had the first thing happen to me so maybe I just misjudged the distance and that's what happens when you go "Too far" with the tunnel. But I know for sure the rubber-banding effect is a bug. No one pulled me out of it, nothing disrupted me. Just the game it's self.
