You’re welcome, melc_av. I agree that it’s sad and I hope that sd2009 will resume work on his project one day, or at least allow someone else to finish the maps with his permission, like Vicpas did with some of the levels from Age of Horror.
Actually, Munich was the first level in the Byblos Maps addon that sd2009 sent to me and Vicpas for private testing, back in 2015 or 2014. This means that sd2009 wanted to use Munich as a level in his Byblos Maps project.
