In both the KS incident and this time, someone asked the artist on Twitter when the next chapter of Window would be uploaded to Mangago, and the scanlation group was mentioned, so now they've decided to drop it because they don't want to get in trouble, and we'll probably have to wait till the official translations are up, around July.
I don't understand why people would think it's cool to ruin things like this with their "aaah gimme moar chapters nao". The scanlation group wasn't doing this for a profit, and mentioning them was a pretty shitty move.

... people would have learned that it's not wise/smart to ask for this type of material directly to the artist. I enjoy reading the stories as much as the next person, but some people need to learn to be patient, I guess. It's sad they -and because of them, we- will have to learn it the hard way.
