2 questions:
what are the numbers below the dates? (1,5,9,14,18 etc)
The week.
and i know that the greyed area's are the one that are "old" items but what's the point of greying them?\
You should only fill white spaces, the gray ones update automatically.
They aren't the old items, they are used to sum up a bunch of items and are calculated automatically, they're grey because you shouldn't fill them, if you do, you break the calculation.
and what will be the punishment of not updating?
The UBSR law already states that in §3.2.1:
If the values are found to be off during an inspection, an amount twice as big as the difference in resources may be confiscated and redistributed to the rest of UBSR's collective storages, excluding Spawntown.
