tag last enemy hit issues when taking fall damage

[higps]

If a player is taking fall damage, the tag last enemy hit throws an error.

I tried to fix this by only doing it if there was a valid attacker. but this generates another error

What would be the best way to fix this?

Moving this to nosoop/SM-TFCustomAttributeStarterPack as it isn't an issue with TF2 Attributes.
You'll also want to check that the entity is non-zero (possibly also resolving the reference with EntReferenceToEntIndex).
