[ASLML] Concealment question

If the timing is irrelevant, then there is no reason for the rules to
differentiate between setting up one category (real units) and then
another (OB granted '?').

I do not know what else to say about this. The rule may be ambiguous in
ASLRBv2 because of the removal of the Q&A. It was not so in ASLRBv1,
which both you and Bruce used to follow. Why do you think the rule was
changed from v1 to v2?

The two possible answers lie with MMP. Either they thought that the Q&A
was superfluous and the rule already addressed the issue; or they
thought that the rule allowed mixing real units and '?' and the (errata
posing as) Q&A needed to be rescinded (i.e. they changed the rule).
Since the rule has not changed, I will continue to play it as if the
rule was meant to be played the same as in v1.
