The volume of the hyperkähler metrics in Theorem 1.1 is comparable to $\beta^{-4}$. If one scales these metrics to have unit volume instead of unit diameter, it is not hard to see that the possible pointed Gromov-Hausdorff limits are either $\mathbb{T}^{2}\times\mathbb{R}$ or $\mathbb{T}^{2}\times[0,\infty)$, depending on the basepoint (see Section 7.3). Thus under this scaling, the nilmanifolds disappear and one sees only a simple $S^{1}$-collapse. However, the bubbles remain the same.
