Local trigger with same event as parent tirgger fires instantaniously

ok lets say a trigger that is fired by a unit using an ability creates a local a trigger and adds the event that a unit uses an ability, the local trigger will fire instantly, how can i make it not fire instantly?

It does fire instantly ? Interesting.
In that case create that local trigger in a separate function that runs on a timer of 0 seconds.

Or try disabling the trigger before adding the event, and then enabling it again when the event has been added.
