Hi,
I receive an error during this process. I am performing a Line Trace from my character which performs fine. I am taking the Hit Actor and then sending an Apply Damage to it. The actor hit is another Blueprint actor, when I try to run “Explode” and “Destroy” animation I get receive the crash below.

I have tested my “Explode” and “Destroy” animation successfully when using OnHit with projectiles, it just seems to be a problem with line tracing.
