random wrong cached vector tiles

[marrylu]

Hello, I have played around with your vtm-android-examples app.
With normal network connection everything works fine but I recognized wrong tiles after having bad or missing internet connectivity. This only appears when using cache functionality.

In the shown example the 3 right tiles are correct (south east Germany to Austria). But the three tiles on the left are wrong cached tiles (different location and zoom level).
This is a random error and can only be fixed by clearing the cache.

Did you noticed similar problems in the past? Couldn´t find anything in existing issues.

Thanks for help or any ideas.
