I have all my fiel at level 7 approximatly if i relocate i lost all ? Some say we give me back my ressource spent ; is that true ? I don't know..
Your fields will be demolished to level 0 but you get most of the resources back... It comes in form of items each worth 2000 resources. Once you relocate the resources will appear in your Heroes inventory and you will be able to spend them in any village at any time you want.
