Play tested in game and in cheat. Observations:
- to get Pendragon to state "Someone's been waiting to talk to you", you have to
hit the trigger at the outer West Gate.
- you can still go through the dialogs with Spencer/DocMoore/Ewald and still
have Tania stuck with Pendragon.
- no exit from Tania's dialog text after telling her Spencer says its okay
(ctrl+C - exit game)
switching between Pendragon/Tania in dialog mode overwrites (local Npc =
FDrpg.get_npc()) variable in dialog loop losing state change of visible nodes
between Tania and Pendragon ( hiding different nodes in each dialog variable).
