Damaged? Is it even possible? I mean serious damage worth mentioning? Cosmodrome is a concrete field, rails and a primitive metal armature construction to hold the rocket. It can't be damaged unless the rocket explodes while on the starting table.

It’s the structure that rolls under the rocket to allow techs to work on the engines and stuff while it’s vertical. It rolls out of the way, behind some heat shielding, before and during launch. Looks like the heat shielding failed or it moved, either way it got cooked.
