so how do you get the odd fruit if the search options are gone in grex room and hallway?
You get them in the supply chest in your room. Random, but usually a few per week.
the supply box disappeared after Nyx showed up. I eventually got one once she returned from the dungeon.
The box is emptied/used by nyx once she arrives. luckily she carries the items with her and you can get them after her dungeon task in the evening ;)
