I got the 7 toolboxes now 2x and they are easy to complete.
All I did what set 4 of my 8 WP on the toolboxes for 2 days and use the other WP's for what I wanted.
and the other 2 "impossible" WP quests are easy as well with 8WP
4x8 on 3h = 32 or maybe 5x8 if you are very sharp for 40 of the 77 demanded items. So again 2 days and you are done
and now for the baskets of groceries: 5 nights of sleeping equals 5x8=40 and they are done.
Maybe it is me but I don't see the impossible part as you are pointing out @Lovec Krys
