Surt - as we agreed with you, we are removing all of those tiles from all future versions of Pixel as it was a misunderstanding on the terms of the license you had assigned to the works. We believed they were an attribute license, which as you recall I emailed you with the credits screen, which I have included below for reference. The screen-shots on that page are the old ones from the PSM release, I haven't started any of the new art & reworking yet.
Please stop being so confrontational about this, we are removing all the content as promised. It was a simple mistake from using an image from OpenGameArt.org. I think you are being rather unreasonable to keep hassling us like this when we have agreed to resolve.
Human error - it happens you know!
