Glad to hear you're liking it. If you could indeed try to record it the next time it happens, that'd be lovely.
However, even though you're satisfied, I'd still like to find the cause of dying and/or supposed issue of not collecting the grave.
Dying to rockfalls has never happened to me while testing, nor any of my beta testers. Theoretically this should only happen if either your client is lagging badly/slow.
Are you using mirror mode or injection?
Are you using invokes?
