I just rescued haer'dalis from Mekrath's lair, so I decided I wanted to look at his stats. I removed Neera from the group, and got an immediate response, despite CHARNAME not being anywhere near her. Without thinking twice, I told her to stay put (instead of heading back to the Hidden Refuge, or wherever it is she respawns).
I've previously encountered a bug where characters walk in straight paths through impassable sections of the map. I believe this is what happened to Neera before I removed her from my party, thus blocking my access to her (and the items she was carrying).
TL;DR Is there a way to access Neera's inventory? Or better yet, get Neera to respawn at the Hidden Refuge?
