Why does GDI AI builds a bunch of Component Towers without upgrades in some TS mods?
GDI AI was programmed to build upgrades on component towers for all their defensive structures. If you have defensive structures that isn`t an upgrade from Component Tower, AI will fail when it tries to build it and it will retry the operation by building another component tower for it. If you still want to have a defensive structure that doesn`t depends on component tower, remove the line IsBaseDefense=yes and AIBuildThis=yes. This might fix your problem.
