Fairy Dust - block for using if no collectibles to shuffle

[kke2100]

I suggest that Fairy Dust will be 'greyed out' like Fairy Fire (home isle) and Fairy Light (adventures) if no collectibles are on the map.

I guess developers forgot to implement this feature

I guess some people don't pin the collectible quest or check how many are left before they use the dust.
Isn't this something like buffing a mine right before it collapses? (Kind of falls into player paying attention)

Considering the cost of using the dust I don't think this is a big issue either way.
