Agree with keeping EP on Willem.
If nothing irreversable occurred during the interturns, it should be ok to open the autosaves to grab demographic screenshots. It's not a bad idea to make a manual save every turn.
We know 5 of 6 opponents? Really??? [edit - I think you mean we know who five of the six opponents are, not that we have met them]
The demo screen says we have 9 rivals. We know about the 3 queens, and the two civs we met: willem, and shaka. We know nothing about 4 unknown. We still need to meet 7 civs.
Very bad idea to open autosaves where a queued unit move is going to execute. In general, I would say do not open earlier files. Its only a violation of rules if something irreversible (like a unit move or diplomatic action, etc) occurs... but best not take the risk.
Agree to keep all EP on Willem for now. We will want to eliminate Shaka asap, in any scenario I can imagine.

And bookcase Billy is a killer.
