Hi there, I really love your White Night mod so far. The references to Penumbra and Silent Hill are brilliant.
I'm recording a Let's Play as I go (I hope this is alright) and suddenly got a copyright claim from this company "Rumblefish"? Apparently a few people have had this problem with them and always with the same part of the game. Do they actually own the rights to any music in it?
