Blueprint references a component that was deleted

Why: A node tries to access the '{comp}' component, but it was deleted from the Blueprint's SCS (Components panel). The reference is dangling.

Fix: Open the Blueprint, go to the Components panel (top-left). Check if '{comp}' is there. If missing: either re-add it (drag from Add Component) or remove all nodes that reference it. If renamed: select the node, find it in Details → Component dropdown → pick the actual name.
