I think this: If reload component is supposed to work better... Then make a unique copy of your components in a copy of the file where they still exist (the "unique" part is optional, I guess, if you make a whole new file). Just pare that component down to something that can be pasted in place--still a component with the same axes as the original.
Paste this new small unique component "in place" into the big landscape file, and then reload it with the full component. (You have to "Save As" the good components meanwhile, so you have the reload copies).
