New Template, New Misbehavior

[RobKamm]

I'm getting a new error this time around: modNeeds: Check Special Cases: Error 5: Invalid procedure call or argument

Here's the template I'm working on:

Ice Weasel, displaycost(variable), cost(),
description(A white furred cold-blooded weasel.),
page(DF5:26),
cat(Fantastic Creatures),
race(Ice Weasel),
* owns(yes), * locks(yes), * hides(yes),
noresync(yes),
gives(_
	+3 to ST:DX,
	+2 to ST:HT,
	+5 to ST:Hit Points,
	+2 to ST:Will,
	+2 to ST:Perception,
	-.25 to ST:Basic Speed,
	-4 to ST:Size Modifier_
),
adds(_
	AD:Claws (Blunt Claws),
	AD:Ice Weasel Bite,
	AD:Double-Jointed,
	AD:Ice Weasel Damage Resistance =10 _
		with {Limited Defense: Common (Cold/Ice), -40%, group(Limited Defense), page(B46)},
	AD:Temperature Tolerance (Cold) = 3,
	AD:Animal Terrain Adaptation (Ice/Snow),
	AD:Teeth (Sharp Teeth),
	PE:Fur,
	PE:Limited Camouflage (Snow),
*	DI:Compulsive Behavior respond "Playfulness" =1 _
		with {You resist on a roll of 15 or less (almost all the time), *0.5, shortname(15 or less), group(Self-Control), page(B121)},
	DI:Mana Dependency,
	DI:Ice Weasel Vulnerability =3 respond "Heat/Fire",
	SK:Brawling =4pts #DoNotOwn,
	SK:Camouflage =4pts #DoNotOwn,
	SK:Stealth =4pts #DoNotOwn,
	SK:Survival (Arctic) =4pts #DoNotOwn,
	SK:Swimming =4pts #DoNotOwn _
),
creates(_
	"DI:Racial ST Penalty, -10/-20, cat(Exotic Physical, Exotic, Physical), gives(-1 to ST:ST), initmods(Size, -10%, group(Size ST), formula(-@if(ST:Size Modifier > 0 & ST:ST::Score > 10 then ST:Size Modifier * 10 else 0)), forceformula(yes))"=5_
),
select1(_
	text("Choose one Ally option: default Animal Ally"),
	itemswanted(1),
	pointswanted(atleast -50, upto 0),
	list(_
		TE:Animal Ally,
		TE:Familiar Ally,
		TE:Wild-Animal _
	)_
)

It runs the SelectX and then bums out with the error. I'm loading it with all of the usual DF files.

For an extra kudos - why is the Ice Weasel Terrain Adaptation still asking for the terrain type?
