Spell animation stuck on loop

[Karzama]

Hi,

Really stuck here and I cannot find the issue!!

I've made a new spell using Channel, and after the unit casts the ability they just stand there looping their spell animation and the target effects loop too

I thought it would be follow through time but that doesn't seem to be it... the unit is meant to be controlled by AI so they need to finish the spell themselves

I've added some debug texts and the spell is only cast once, just the unit gets stuck...

NOTE - They continue looping even after the target has died too...

EDIT- I've got round it by forcing the unit to Stop after casting the spell, but I'm still confused!
