Locked Target while Player Dies causes Unhandled Exception

[rojahuchez]

Fristly - Thank you for this amazing plugin - It's a beautiful thing!.
When I have the target locked and the attacker kills the player (who has the target locked on to the enemy) - the editor crashes with this error:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000001c8

Thank you for opening the issue @rojahuchez

I wasn't able to reproduce the crash in both fresh 5.2 project and Lyra 5.2.

However, I added a few nullptr checks in the method that was crashing on you, it's available on the master branch and you could test it if you'd like (You'd need to git clone the repository into your Lyra Plugins/ folder or pull to latest if you were using git already)

This worked @mklabs!!! Targeting while dying in Lyra does not crash anymore so those nullptr checks solved the issue for me.

Thank you so much for doing this!

🎉 Great! Thanks for testing locally, I really appreciate it you could confirm the fix locally.

I'll prepare a release and submit a new build to Epic for the marketplace this week.
