when upgrading these It is posible to go past your resouce capacity to install the upgraded unit. For example:  Once you upgrade this to lev 3, you can no longer install a lev 1 or lev 2 Turret. At lev 3 it requries 10million thor to install it. If a player does not have the capacity to store 10 million thor, then its imposible to benifit from the upgrade, because it cant be installed, and you cant install a donwgraded version either.
