Nocturne's E allows casting beyond maximum range

Description

Nocturne's Unspeakable Horror (E) can be cast from significantly beyond its maximum cast range (expected 475u in the 1.0.0.126 client).

The ability activates successfully from ~600u, consuming mana and going on cooldown, but the tether breaks instantly.

This happens even after changing the tether range in NocturneUnspeakableHorror.cs to the version-appropriate 525u.

To Reproduce

  1. Enter game as Nocturne
  2. Level up E
  3. !spawn minionschaos
  4. Stand at least ~600 units away from the target
  5. Cast E
  6. Result: Spell casts successfully, mana is consumed, cooldown is applied but the tether immediately breaks due to the range check

Note: The same behavior occurs when casting E on Annie Bot or jungle creeps.

Expected behavior

If Nocturne is out of range, he should walk towards the target until he is within maximum cast range, then cast Unspeakable Horror.

He should not be able to activate his E from outside the allowed range.

Best example I could find at the 9:37 mark.

Console Logs

Added debug logging on OnActivate() and SpellBuffRemoveCurrent(owner) on NocturneUnspeakbleHorror.cs and got this over two casts:
