No. Not through shutting down nor restarting at an earlier time. Afterward I went into the GECK to see what was going on. Seems there were some quest variables that never got checked. Probably cause I ended up doing something that the game didn't expect, yet was still given the dialogue option to view their inventory. (From checking around the net seems others have had this issue too. Could be a bugged quest)
Anyhow, I ended up checking the dialogues result script that checks for those certain variables and blanked them out via the semi-colon. Saved the plugin so I'm able to view the inventory as intended.
So yes I got the inventory to show.
