Cover Corp received a copyright claim from Capcom on a 6 month old stream of Ookami Mio's. As of about 9 hours ago they went into Brown Alert mode and were in the process of deleting everything. Working casualty list here. Korone and Subaru have been effectively defenestrated into the dump truck.
EDIT: Someone more versed in runes says it was Konami or someone pretending to be; I can't read any of it so I don't know personally.
It's clearly one of those fake company that runs on strikes and blackmail. Capcom wouldn't waste their time on a 6 month old stream.
Screenshots have appeared showing a pretty wide swath of flags, not just that one stream. Operating without any statement from Cover has lead to a wide array of speculation. Personally, I put nothing past Konami ruining anything they feel like ruining.
