What happened to top/tracks and top/artists?

[Otorii]

Hello,

since the 19th of March, these 2 api

https://api.spotify.com/v1/me/top/artists

https://api.spotify.com/v1/me/top/tracks
return very different results for the time_range = long_term, almost like if the long_term instead of being years is some months.
Is this a bug or is it the intended behaviour?
Thanks
