One possibility: Its been suggested that the relics have a limited timespan that does not reset based on being taken. So if the Hammer relic was taken, taken, and recovered, it might only have one tick left, which passed just after the guardian was killed. This might have subsequently forced the guardian to reload into the game to hold the new relic as it reloaded.
