Just to be clear :
The effect itself , that reduces the health works and stop correctly, it’s only the gameplay cue actor that reappear.
It was a good idea worth trying, however I get the same behavior, maybe there is something that changed between our versions.
On Collision with an item, I apply an ability using ABS
the ability gets the ABS from the player and apply the effect on it
The effect gets applied correctly ans stay for the right duration, but I received the same order of message that reactivates the Polled GameplayCue if I play with the timings (0.5 vs 0.51s) .
For anyone interested I have implemented a simple watchdog to recycle back in this case.
On Activation I set a flag that is removed only when all Effects for that cue are removed
Then when On Execute happens after the fact, I Recycle the actor again.
Thanks @ezgoin for sticking with me.
