Instant(No Target) Channel Ability acting weird

[Pugnadeus]

I have a trigger that stops the unit when he begins casting it if he has no rage. The trigger shows an "error" message to a player. I attached the trigger in the post.

Now, when I use most abilities, it works fine, but the problem is when I use Channel abilities that are Instant(No Target) I get 1000 error messages and the "stop" function doesn't work, along with lagging the map.

What in the world would cause such a thing?

Can you include a screenshot of the ability data?

Stop function doesn't work if you don't put a wait before it, use 0.00 seconds. (Note it will never be 0secs in fact, it will be around 0.20~30)
A unit begins casting an ability -> A unit starts the effect of an ability.

If your spell is triggered you could also do Unit starts the effect of an ability and check for rage and id there is rage proceed with the spell and if not just reset the ability cooldown
