I didn't see page 2 when I responded last, so I'll just add here, you are not supposed to play any scenario more than once. I realize we are limited in scenarios, but that doesn't mean that the game is designed where you run through curse of the rougarou four times while idling. That should be done as a pure standalone or as part of a different campaign.
Yeah, but if you take the same Investigator on multiple campaigns, he could run the same side-story more than once. I guess if you treat it all as one big campaign as you suggest, you would not run into story asset problems either. So either you treat them as separate campaigns and return story assets at the end of each, or you treat it as one big campaign and keep them, but you won't be able to ever run a side-story again.
I remain convinced that bringing Weaknesses over from campaign to campaign underpowers your investigator greatly though. But maybe that's the intent.
