That is EXTREMELY disappointing.
We have been using one of the most reputable art houses in the industry, that works with Blizzard, Riot, Epic, Supercell, etc…
Their work goes through a number of levels of QA to try and catch this stuff. The 2 other times this has happened, the artist has been removed from the company immediately.
I will be taking this up with them today. We are all incredibly upset about this!
