Unreal Engine 4.13 (and 4.12) broke my Grenade behaviour!

Does your grenade class have a subclass that overrides ShowExplosion() but forgets to call Super::ShowExplosion()? Or if you override it in a blueprint, does it call Parent: ShowExplosion?

No, it doesn’t

So the problem is inside the ShowExplosion() function. So, now do the same as with AProjectile_Explosives() - logs between all lines in the function.
One question: after the grenade explodes, what happens, I mean, what process do you use to remove it from the scene?

I added UE_LOGs to ShowExplosion() as well.

I tried firing two grenades. The first one exploded, the second one didn’t. And so this is the LOG:

First grenade LOG (exploded)

LogTemp:Warning: Explode() called
LogTemp:Warning: Pre check 1
LogTemp:Warning: Post check 1
LogTemp:Warning: Pre check 2
LogTemp:Warning: Post check 2
LogTemp:Warning: Pre ShowExplosion()
LogTemp:Warning: ShowExplosion() called           // <---- oh, that happened!
LogTemp:Warning: CHECK 1 PASSED
LogTemp:Warning: CHECK 2 PASSED AS WELL
LogTemp:Warning: Post ShowExplosion()
LogTemp:Warning: Explode() finished
LogTemp:Warning: ShowExplosion() called           // <---- WHAT??? It happened again?!
LogTemp:Warning: CHECK 1 PASSED
LogTemp:Warning: CHECK 2 PASSED AS WELL

Second grenade LOG (didn’t explode)

LogTemp:Warning: Explode() called
LogTemp:Warning: Pre check 1
LogTemp:Warning: Post check 1
LogTemp:Warning: Pre check 2
LogTemp:Warning: Post check 2
LogTemp:Warning: Pre ShowExplosion()
LogTemp:Warning: Post ShowExplosion()
LogTemp:Warning: Explode() finished

As you can see, the difference is pretty obvious.

In the first log, after

Pre ShowExplosion()

, the ShowExplosion UE_LOGs are getting printed.

In the second log, after

Pre ShowExplosion()

there quickly comes

Post ShowExplosion()

with no trace of the execution of the ShowExplosion() function.

As for the fact that the ShowExplosion() is called twice in the second log, I think (but not sure) it has something to do with my multiplayer. Because I was running server+client
