I'm having a problem with this map only showing part 5 in my addons folder, I'm wondering if anyone has the same problem as me. I've already tried downloading a different map and with all the parts and it doesn't show up at all.

Summary of the story: I downloaded The Bloody Moors collection (part 1-5) but I only see part 5, and when I try to launch a game on part 1 it kicks me out. (Thank you in advance for helping me out)
