I've been having weird issues with when routes are drawn on the map. These have manifested in 3 different ways: 1. It will draw part of the route on the map. Some segments will be missing. 2. The route is completely missing and only the destination flag is shown. For these 2, it will sometimes show the full route if I switch to a different zoom level. 3. The map shows the wrong route. Sometimes it's the route for the previous place I navigated. Sometimes it happens if I miss a turn and it has to reroute. Are you seeing this? It seems like there are bugs in how it decides to expire map route tiles in the cache. This doesn't seem like something fixable at the service center.
