I can't find the entrance to the Newfound Spire, the first spire in the Lost Spires mod.

I found a Youtube video that shows the entrance is underground:

However, when I go there, there isn't any steps that lead down. It's just grass.

Why might this be the case?

Is there a way I can 'coc' to that location, and if so, what's the location code?

AFAIK it is supposed to be like an Ayleid ruin, just go down a spiral staircase and then enter through the Ayleid-style door....

It may be a mod conflict. Are you using any UL (unique landscapes) mods? If so, are you using the relevant patch for Lost Spires?
