Nether warp debuff reapplies itself for another 20 sec when entering the teleport area

[Vargares]

I'm aware debuff is set to 10 sec and is meant to reapply once to provide 20 sec teleport immunity, Issue is that when a unit moves over to the teleport area the bug refreshes itself for another 20 sec. (so you can end up with nether warp duration +20 sec no teleport). If you place another nether warp from a diffrent affinity below the unit to chain teleports a moment too soon, your second cast is wasted, beacuse the buff will refresh itself and the durantion of the new teleport will run out before new instance of 20 sec debuff passes.

Severly limits use of double nether warp (two affinity) in decks and some other cool shenanigans in mp.
