GetIsIllusion in lua modifier causing crashes. Plus, tempest double is not supposed to behave like illusion. It's considered hero for spell interactions.
EDIT:
Also,
Since 6.87 tempest double is not spawned every cast. It is respawned after the first one resulting in the tempest double's cooldowns not being reset on new casts. i.e. old tempest doubles cooldowns need to carry over to the new one. I can't think of a efficient way to do this so i'll leave it here for someone better to fix it.
