      abstract     = {We consider type IIB string theory on $\mathrm{AdS}_5\times
                      S^5/\mathbb{Z}_{L}$ orbifold spaces with generic $L$. Recent
                      localisation results in the dual 4d $\mathcal{N}=2$ circular
                      quiver gauge theories provide us with strong coupling
                      expansions of certain correlators involving twisted half-BPS
                      operators. To leading order, these results have been matched
                      to an effective theory for massless twisted string states,
                      which can be constructed by resolving the orbifold
                      singularity and considering localised supergravity modes on
                      the resolution cycles. Applying this reasoning to subleading
                      order in strong coupling, we observe that for $L\neq
                      2,3,4,6$, a naive reduction of the 10d $(α')^3$-correction
                      does not result in the correct coefficients to match the
                      localisation result. We explain this mismatch by the
                      appearance of twisted sector resonances in string amplitudes
                      involving external twisted sector states. We perform the
                      low-energy expansion of a ``twisted'' Virasoro-Shapiro
                      amplitude and recover the expected coefficients, suggesting
                      that the orbifold resolution and the low-energy expansion
                      can not be interchanged directly. Finally, we comment on the
                      long-quiver limit, $L\to\infty$, in the context of the
                      low-energy effective action.},
