that is a glitch with CNME, you can fix it yourself if your handy with the construction set, but i've never really looked into how, since i dont use CNME(i just use the coc command), but right now im working on a mod that will implement a way to get to morroblivion and more map markers(hopefully for all the spots), and some other things, if you wanna know more just have a look at the "starting up a mod" topic in the morroblivion mods subforum
