The first reward.. is
building material 18,000 (this number maybe its relevant to cities/lvl etc) for 120 favour..
It is the only reward that cannot divide by 25...
thus you are keep currying 5 favour..
It is a bit frastrating that you cannot have round numbers.. unless you use 5 times this reward..
Could you increase a bit the quantity (for example 19,000) and set the cost at 125????
