I am very new to mapping in Radiant Black. I am having troubles with a few traversals in the first room I have built. There are three in total, but only one is working. I made sure that all three of the traversals are up to date and compatible with every spawner (i.e. none of them are Der Riese traversals).




There are two traversals for going down and one for going up. Of these, only the one where zombies jump from the ceiling works.
