It seems you changed multiple variables at once?  (I assume that was you.  There was no way to tell who made the changes.)  The wording in the Ruleset may be a little ambiguous, but I know that AG’s proposal was under threat of VETO if it allowed a single Traveller to change all the variables at once.

Yeah, I think that was em. We need some mechanism to determine who has changed what, short of looking at the IPs. Perhaps we ought to sign our changes?

gee, I dunno.  or maybe just put it in the original GNDT which automatically signs changes.

* 1: I did it on purpose (altering 2 variables) to stress the current rule wording. I guess a CfJ is in order if someone disagree that

...change the values of ‘x’, ‘y’, ‘z’, ‘w’, or ‘t’ as permitted by any of the legal Formulas...

allows the changing the value of more than one value (as per “values”) acording to more than one Formula (as per “formulas”).

* 2: We could just replicate all Travellers and their passwords to the second GNDT. I didn’t do that right away ‘cos I guess a Proposal is needed in order to do that and I don’t have a Proposal slot.

This is bad.  A single formula that linked all 5 variables could then be used to change 4 variables all at once.

Not at all, but 5 formulae that each gives one of the variables on its right would make possible modifying all five at once.
