Saw your other post. At a district level event it would be the same as a council event, NCAP variances apply. 

Does the troop have written expectations of positions of responsibility? Are there APL's that can step in for the sick and uninterested? 

I would advise you to chase this as a program improvement point and not a punitive point. Raising it such as "I am concerned that without proper messaging and clarity the camping variance from the council event that our CC utilized might be viewed as allowed outside an NCAP environment. We don't want to normalize the view that we can just camp with who we want when we want. I want to make sure that in order to follow Safeguarding and the GTSS we understand that unit level camping outside of an NCAP regulated event doesn't allow this." versus "CC did this and I don't think we should allow it. What are we going to do to prevent this from happening again?"

Normally no. If this were a joint unit event outside of an NCAP environment she would need at least 2 leaders and 2 scouts from the Scouts BSA program level (preferably all from the same unit). But under a council event that is NCAP regulated there are all kinds of variances. 

I see this, even with my own kids; I am constantly telling them no voice-to-text is allowed which forces them to have to spell at least.  We're seeing some gap issues at the troop level still but we've undone the damage done at the pack level (Just instituting correction in the program from an adult standpoint). We're one and a half years out from the last covidish era patrol aging out, I suspect if we keep focusing on instituting the program properly on these successive crossover patrols we'll eliminate all of the problems as well.  For skits one of the things I have noticed is that if we give scouts advanced notice and remind them to have something in the pocket for a fireside program they come prepared, if we ask them on the campout to have something they go right to the struggle bus.
