I noticed a while back that the Alpha Team character models underwent a suspicious change during development.
Let's look at our buddy Flex here. This is a screenshot from the released game. Like all other minifigures in the game, his legs protrude directly from his body. There's no hinge holding them to the inward sides of the legs like on real minifigures.
Let's look at some beta screenshots.
Ah.
Tonight I noticed something more - if the game is loaded without any textures (aside from lightmaps in this case, though it can do without them, too)...
... Well, would you look at that.
Curious if part of the body texture was simply turning it transparent (it didn't seem so, as there were no transparent pixels whatsoever on, say, Dash's body texture), I loaded the game with only Dash's body and head textures.
Nope. The geometry in question has actually been given a different texture called NoPrick.tga. It's a 4x4 fully transparent texture that renders the pricks nixed.
Sadly this texture is shared between all minifigure models, the original UVs have not been retained, and it's also used for some mysterious invisible trapezoidal geometry on a few baddie models. Furthermore, all the prick's materials have a slight greenish tint for reasons unknown.
So, loading Dash's body texture in the place of NoPrick.tga results in this:
It appears as though if one wanted to restore the pricks, one would have to wrestle with the models fairly extensively, in addition to the question of why they're attempting to do such a thing in the first place.
That's all for now! Tune in next time for "Wait, why does mf_main_loc.nif in LEGO Universe have nodes named loc_lt_nipple, loc_rt_nipple, loc_bellybutton, loc_naughty, and loc_butt...?"
