Hi there,
Lake Taupo is one of New Zealand's most prominent geographical features, and currently in the Esri basemaps it disappears at 1:3,301,061 which looks a bit weird. This is also the case for other large lakes in New Zealand.
E.g. 1:2,112,679:


1:3,301,061:


Could you please re-cache the basemaps so these lakes are shown at scales smaller than 1:3,301,061.
Cheers,
Marc
