The command keys D and V don't actually control a party member when scripts like "Thief Controlled" (theif0) and "Cleric Controlled" (cleric0) are active. A Thief will neither continuously search for traps or hide in shadows when idle. A cleric will not turn undead. For a couple days (maybe 12-ish hours or play time?) after I initially started using these scripts, they worked great. I was so excited to finally have Imoen constantly try to stay hidden and ready to backstab! But now they stopped doing their "idle" actions pressing D and V don't change their behavior. I've tried changing their scripts to something else and switching back, but that doesn't seem to work. They do seem to still engage enemies as described in the script.
