HLR Reconstructed problems

I am having problems with HLR Reconsntructed. (Remember that mod.) For some reason, none of the SNPCs seem to wander around, even if they are on a noded map (namely, this map:

). This is not a problem with the original Half life reinnessance addon. (That has its own problems, such as how all the snpcs are completely non-hostile to everything else.) What should I do?

Also, do you know if there is a way to save added NPCs into a save file without them glitching up (i.e. not being able to “wander”) upon being reopened? I am trying to build a zoo, so this is frustrating.
