each time I open my map, I have the following exception occurring multiple times :

Thanks for the bug report @Thelm76! Could you provide some additional information please? - how do you create your CachedTileProvider? - what CacheStore do you use? - what tile provider do you use?

edit: I've seen your PR. Thanks didn't knew that dio returns a -1 for total bytes.
