Thanks for the update Zackman.
I was part of the team that figured out that holding those hulks open DOES in fact re-sync spawn the field, so all the hulks spawn together. This situation occurs naturally with any restart and continues "most" of the time. Occasionally the hulks become out of sync in their spawns, which can occur for any number of reasons. Anyone interested in mining this field "should" appreciate the hulks spawning together as they all have a better chance of getting what they are after.
In this case, someone got to the hulks first and mined them (with the exception of debris, which can be found MANY other places). Holding the partially mined hulks open does not extend the spawn timer at all, so is of no benefit to anyone, it simply allows all hulks to re-pop together for the next person to find.
All that said, no greed involved here and could/should have been handled in-game by a simple "tell" or local chat instead of the flaming that occurred in general chat, followed by this posting.
