When the build tick occurs, most resources that are left over will spoil and be lost. The amount that is carried forward is the lower of the maximum percentage of resources or the maximum capacity of that tier of storehouse (see table in previous section).
For example, if a clan has a tier 1 storehouse (maximum capacity of 1,000) and they have 10,000 surplus wood, they keep the lower of 1,000 or (5% of 10,000) 500 wood. Similarly, if a clan has a tier 7 storehouse (maximum capacity of 3,000) and they have 10,000 surplus wood, they are only able to keep 3,000 despite 50% of 10,000 being 5,000.
