Yes, i used the VX demo version to find this as i've used a friends VX version when i first started using the RPG Maker engine as he didn't use it back then, not sure if he use it now either, but pretty sure it will work like this on Ace as they have a bit in common from what i can see. But i haven't taken a look at Ace yet, but im pretty sure

And will make a demo in VX now, will probably be ready within 30 min - 1 hour i guess

Edit:
here goes, and i was doing a lot of Variables where i added points earlier for a collector quest (helped out a friend as im not a fan of them), so you could originally just do it with the "Conditional Branch"
I also added so when all items are gathered on the second map, a new person will appear (Event with parallel process)
anyway,
here you go 
Will be available as long as i have Dropbox activated, and will just have it active till you've downloaded it if not longer if anyone else wants it
