Genres from artists have been removed

[Morganic1]

It seems that many artists have had their genres reworked or removed completely.

That means that the /artists={artistIds} endpoint returns very different results than yesterday 

E.g. Tove Lo, London Grammar and Corinne Bailey Rae return no genres as at all.

Is this an intended change? This has significant impact on mine (and likely many others) applications.

I've noticed this too, seems like many artists either have no genres or the wrong genres assigned to them. Definitely a major bug
