TowerSectionComponent.GetPreviousTowerSection().GetPreviousTowerSection().GetPreviousTowerSection().ClearSectionTemplate();

I tried to take a short cut and it quickly backfired.

What I should be doing is use a dynamic array so I can just do
TowerSectionComponent.GetSectionFromOffset(-1)
TowerSectionComponent.GetSectionFromOffset(-3)
TowerSectionComponent.GetSectionFromOffset(5)
and so on.
