That would not work, at least not according to the theory I'm talking about.Didn't we already get a guy with all 64 or so data items to log in on solo, and nothing but the original obelisks were lit?
The theory is that there are 3 different types of site and there are 3 each of them to be found. The theory goes that the data you can get in solo is "chapter1" data. The theory is that you need all the "chapter1" data to unlock the next set of obelisks, so you need the 13 from the first site, 11 from the new type of site, and ? from the final as yet undiscovered type of site, all together this is X pieces of "chapter1" data where X = 13 + 11 + ?.
The extra obelisk data being unlocked in open/pg is "chapter2" or "chapter3" data, the stuff we're not supposed to unlock yet, and it doesn't count as "chapter1" data. So, no single commander will have X pieces of "chapter1" data yet. But, multiple commanders together do have more than X pieces of "chapter1" data and I think the "bug" is that the game is counting the data on all players in the instance and not discarding duplicates, and therefore getting a figure which is greater than X, and so unlocking the obelisks early.
I could well be wrong tho.
