I have tried my best to follow theirIntellectual Property Guidelines e.g. make it clear that this is unofficial project with no-charge digital distribution etc.
I would be happy to arrange to get a licence from Games Workshop to develop the project freely perhaps by re uploading with more content under said licence, but until they contact me or the project gains significant views/downloads etc then I dont expect any issues in the short term
Hope that makes sense and thanks for the interaction and interest of my little project :)
