Why does this crash:
AActor* TActor = PrimaryTarget;
if (TActor)
{
FString str = TActor->GetName(); //<--DMagic!AProjectile::DoSeeking() line:183
}
With this error:
Access violation - code c0000005 (first/second chance not available)

EDIT:
Ok I got some more info.
The crash only occurs if I spawn 25+ of the projectiles this code is in from a for loop.
Any less and there is no crash.
While that presents a work around for the time being, I do plan on having 25+ projectiles spawned at some point, so I still need to know how to fix it.
EDIT2:
MORE INFO:
This error occurred once between two play tests under the sames settings and conditions. 8 projectiles spawned.
