This must be a rare occasion. We have this running on our server a lot longer before I put it online.
Maybe it' s when a player mounted a decayed vehicle that's just about to despawn.

As reviewers do not like excessive null-checks, I will take note of this but will wait to take action until I get more error messages.

It doesn't seem to be about another subcall within this method as I don't see it begin mentioned.
I had remarks beforre to remove some null checks in another plugin but I could add null check on the entity and player add start. I don't see what I could do else at the moment.

Maybe it has something to do with scientist in chinook? Although we don't have errors. We'll keep an eye on it. I'll check balloon and sedan. I didn't do that, we don't use them but it should be cought by the type checks.

I'll have a look.
