The custom undead creatures from the Undead mod is not showing up in my tombs ingame, i tried a few different tombs already and all i see are vanilla undead creatures. The only other mods that affects the leveled lists are ranked dremora and mca 8.1 but they should all be compatible with each other since they are released by the same creator and he even suggest to use the undead and ranked dremora with mca on the nexus download page so it has to be 100% compatible. Im only level 6 right now so maybe the new undead creatures only shows up when im higher level? but than again i kinda the custom undead creatures already showing up in the older version of mca that includes it even when i was low level.
