I am starting a new save that will use the Building up Uvirith's Legacy plugin and the Less Generic NPC plugins, and I noticed that there is both a normal LGNPC Tel Uvirith plugin and a version made for Uvirith's Legacy.

Anyone who knows which one I should use with BuUL?

It shouldn't matter, because the Uvirith Inside/Legacy plug-in for LGNPC only alters one npcs position in the lower tower. So if you're not using UL or UI, you don't need that version.

I've fixed this in the upcoming release of UL, so that you don't need the UI version of LGNPC anymore, but the current one available (Beta 1.10) still requires it. BuUL alone, does not require it. Just use the normal LGNPC version.

Ok, thank you for your help.
