Okay .. I just got annoyed when I found this out. I mean, I knew this existed I just didn't realize how annoying this was.
A hero's mansion lvl 15 cost is Screenshot by Lightshot as you can see.
The highest is 37935. Are you kidding me!!! Lvl 16 of Warehouse has a capacity of 37900. I have to upgrade one whole level for 35 extra resources?
Are you trying to bully us, Travian ..? This is absolutely ridiculous.
Bring the cost of lvl 15 Heros mansion to the capacity of lvl 16 warehouse. Please.
