Why not post a short animated GIF or video here?

No video but… I was going through the “one line can fix this” problem with the positioning of the impulse and I approached it in a slightly different way. Instead of attaching it to the rootcomponent, I added this one line above the firing of the impulse…
ExplosionForce->SetWorldLocation(Hit.Location);
… to the OnHit function. That worked fine and I was pretty happy with that. Are there any drawbacks to do it this way?

I found the solution in 5 minutes. The caching bug took me another few minutes to solve. Actually, I get a bit worried about all these engine glitches. Today I saw a guy on Twitch rage quit his broadcast because all his BP’s got somehow corrupt. Do one needs to know all these bugs by heart to be efficient with unreal? 
What do professional developers do? Is Unity any different in that regard?
