[BUG] Teleporting to a tower as it falls doesnt cancel the teleportation.
Just happened in a game i played. To reproduce, teleport to a tower and make someone else destroy it as your teleport reaches the 3 seconds mark (Where it would, before its nerf, finish channeling)
The teleport effect will vanish, but the teleporting player will still complete the channel half a second later, appearing near the ruins of the tower.
