  We evaluate the backreaction of O6-planes in scale-separated $\text{AdS}_3$
flux vacua of massive Type IIA. Using the appropriate flux scaling we show that
the corrections to the various background fields and moduli are controlled and
subleading when going from smeared to localized sources. Similarly, the
backreaction corrections to the scalar potential are parametrically small in
the scale-separation limit, assuming always that the near-O6-plane
singularities will find a resolution within string theory, even in the presence
of a Romans mass. Our analysis is based on the equations of motion and
therefore applies also to the non-supersymmetric vacua.
