Hey MofoMan22,
I think that what you are seeing is two of your grenades trying to attach to each other:
-Grenade 1 receives OnComponentHit event and attaches to grenade 2
-at the same time, Grenade 2 receives OnComponentHit event and tries to attach to grenade 1
The second grenade though can’t really attach to the first one since each object would be attached to each other “forming a cycle”.
I am not sure if you’d like your grenades to be able to attach to each other - (if not) I would suggest adding another branch checking if the HitActor is of “StickyGrenade” class
