Follower won't follow into mod I recently made.

[keyah111]

I have been trying to get my follower to go into a mod I recently made and Lydia won't enter but Sofia on the other hand will travel into the mod with me and follow me everywhere in the mod no problem. I use console command "moveto player" to get Lydia to where I am at and once inside mod she moves around freely unhindered...what might be the issue and where do I start to correct the problem: Skyrim side or Mod side? One thing I've noticed in Navmesh on the Skyrim side was a set of lines, yellow lines with green bars running right in line with my entrance...would that be the cause of my follower entering mod problem?
