Killap,
I'm seeing a handful of issues and potential issues at the EPA:
The toaster gives your character an ability - normally in Fallout 2, when you get an ability for finishing a task, it shows up in your list of perks, but as far as I can tell, there's no record of this ability at all in your character sheet. Have you considered making a perk for this new ability?
Unclogging the vents (Violet/yellow level) is really non-intuitive, because the hand icon only appears if you click just on the correct pixel (or small grouping of pixels). The vent itself is very large, so there's no reason why the hand icon should be activated by such a tiny portion of it.
Kitsune is supposed to be best with unarmed combat and second-best with melee weapons, according to the RP walkthrough. <s>Why can't she use "unarmed" weapons like the Mega Power Fist? I had one to give her, but when I tell her to use her best weapon, she won't equip anything. I haven't tried giving her other weapons yet (regular power fist, spiked knuckles, etc), nor have I entered combat with her yet.</s> EDIT - I realized that she won't equip unarmed weapons because her initial weapons preference is "ranged then melee." Given that her primary skill is unarmed, her secondary is melee, and her lowest divulged combat skill is with small guns, her default preference should be "unarmed." It doesn't make sense for her to first use her worst weapons.
