if you Teleport to a tower with the Teleport spell, but it is destroyed before your teleport finishes, then you will get the cooldown of Teleport, but won't actually teleport.
this has been in the game for over 6 years and is not a bug
That is the mechanic of the spell. has been since teleport first existed
As already stated, this isn't a bug.
Teleport goes on Cooldown when you cast it. If your target is destroyed(Tower), it fails but stays on cooldown. If you get killed or crowd controlled it fails but goes on cooldown. You used to be able to cancel it as well, causing it to fail and go on cooldown - But that was removed... Last season? Season 7? I dunno, sometime though.
TP has literally been that way since I started playing in 2014.
No bugs, I promise.
