Hive Leader 2: Fall of the Empire

Hello everyone. I have a problem with this map. I can't escape from the dungeon. I can only go down. On the surface, the hero doesn't appear near the dungeon, but inside the dungeon's textures, so he can't move left or right, only down. If you wait for a few weeks, Loran arrives with 3,000 devils, and that's the end. He gathers troops normally within the dungeon itself.
