Bug fix in map tiles in standalone: the map has been blank since commit 01ae916bad r/17324 (Nov.18, justincc). But the root cause comes from commit 02e54c57c4 Author: Oren Hurvitz Date: 7/22/2011 

This is a nasty situation. The map tile UUID is, in principle, stored authoritatively in RegionSettings. However, it also needs to be stored in the Grid Service because that's how other sims can retrieve it to send it in Map Blocks to non-V3 viewers. So every time the tile image changes, that change needs to propagate to the Grid Service, and this is done via RegisterRegion (ugh!). Interestingly, this problem didn't affect grids because by default AllowRemoteDelete is false, so the prior images aren't being deleted from the asset servers -- but they were not being correctly updated in the map either, the map was stuck with old images.
