Hi,
I was thinking that sometimes my builders are idle until I collect enough money to upgrade, and this is increasing with higher levels.
why can't we lease the idle builders within the clan members for money for a period of time, the owner decides the period and amount, the system can define a minimum and maximum.
In addition, if the period is due and the builder was not done yet, the upgrade is paused, and the user can start where that builder stopped.
