The 'NPC turns into a container' bug, usually can be fixed manually in game: http://www.nma-fallout.com/threads/fo2-engine-tweaks.178390/page-123#post-4065716I don't know if this was a bug with the game or the patch; but in and after a long battle, some live NPCs would have their talk option replaced with loot. This becomes a big problem when it affects companions because you can not talk to them and they would only follow you to the next map. This has happen fairly often; but one time, it nearly cost me a lot of progress. I gave Lenny some vitamin .223 hoping for a cure or at least freeing up a companion slot. It worked and I reload decided to go for vitamin BB which worked just as well.
Already fixed in sfall 3.7, the next RP 2.4 should have the updated sfall.
