I had a standard chest at 0/100.
I ran the first stage of Find Battle Items
I ran the first two stages of Mount Umber
My chest was still at 0/100!
I then filled the chest by farming the map and that worked fine.
I’m using an Android phone and running version 35.0.0 Build 1406
Was this an intentional change in the game or is it a bug? I haven’t found any reference to it on the forum nor in documentation.
