Since updating both the GECK and the game to the most current patches I've found that one of the selections on the companion wheel no longer works for my custom companions. That being Open Inventory.
Applying stimpaks seems to be working, the other options I hadn't done anything with yet, as all the orders could be done through dialogue anyway so it wasn't really a priority at the time. I was more concentrating on Follow, Wait, Sandox and Share, making sure they were working properly. Which they were.
I haven't worked on either plugins with the GECK since patching, I did open both of them up to see what's going on, but there doesn't look to be anything wrong. I just don't know why it works for the vanilla followers but not mine all of a sudden.

I think the latest patch broke it, but only because it was the only different thing I did between play sessions. No new mods were added or removed, my load order wasn't re-ordered, it was basically quit playing, patch game and GECK open FOMM to put FalloutNV.esm back at the top of the load order, launch game, play a bit then discover problem.

I've also put my entire load order through FNVEdit but both plugins have no conflicts/issues with any other mod so I really don't know what's causing the inventory share to not open using the companion wheel. Has anyone heard of that particular issue before and possibly even know what could be causing it?

Thanks!

The inventory option invokes a specific topic whcih one should use in their own Quest, "FollowersTrade" is this topic.
one adds the script into the response, OpenTeammateContainer

All the vanilla followers are rigged up using VNPCFollowers quest, pretty much.
One can find good examples of how to in there.

I know all that. Like I said, it was all working fine before, and now it's not, since patching both the game and updating the GECK. I didn't find a GECK changelog so have no idea if they actually changed/broke anything, or if it's just me.

Has it happened to anyone else?

I checked David in my WIP mod (at some stage in the quest he is a follower) and his inventory opens flawless if I use the wheel. I haven't worked on this mod for ages (2 updates or so) and I expected a lot of troubles but surprisingly there weren't any. NV is at the latest patch.

I use the standard configuration which mostly is a copy of Boone. David has his own follower quest (followerstrade topic), is a teammate, and OpenTeammatecontainer 1 in the Begin script of the dialoge.

Mine broke too and I replaced 'OpenTeamMateContainer' with

RHKWendyREF.OpenTeammateContainer 1

Ah okay, thanks for the replies. Mine's just OpenTeammateContainer in the result script box in the dialogue topic. Needing the 1 must be a new thing then.

One of my followers is a FO3 'port, I had a bit of fixing up to do, although with the help of another modder who told me what could be scrapped/doesn't work for New Vegas.
My other follower is really basic, an ex-player character that I just threw together for a friend. As long as Follow, Wait, Sandbox and Trade worked that was all that mattered.
I haven't copied from any of the vanilla followers, I was happy that I didn't need anything special to invoke the companion wheel to begin with - as long as the NPC is a teammate that's all that was needed which is good because scripting is not my forte

Anyway, thanks for the help :goodjob:
