Death

Not something we control. Chinook doesn't always drop crates though.

Everything seems to be in order. If you have steps to reproduce that'll help.

Is that a public quarry?

Not sure what would cause it to despawn but we don't control resource nodes so this would be a game issue.

I've passed this report off to the Facepunch devs.

This is something out of the scope of work we do. I've done a lot of flying but don't think this is really an issue. If you provide more information I can pass this off to FacePunch devs.

Would be a parenting issue within the game. I could provide a temp fix but I'm pretty sure this was a freak accident. Either way, sounded like a good time to me.
