Tile caching issue

[abendebury]

Sometimes at a certain zoom level it seems like a tile is not available (see first pic). However, after zooming out, the tile loads at a reduced zoom (see second pic), then after zooming back to the original level the tile remains (third pic).

It seems like it should either always be shown (if it is not in the local cache) or never be shown (if it is not in the cache).

actually this might be confounded due to the wifi connection, let me try to replicate without data and see if I can reopen with a better example

Even if you can reproduce this again, it should not be an issue with this app but rather with the render library https://github.com/tangrams/tangram-es
