Either no one knows how to fix this problem, or no one will take the time to help me.
My bet is on the second one.
Because of how hopeless you seem, I'll throw a little idea.
I know little of TorqueScript or how the Torque engine works in general, the same goes for the inner workings of Blockland. But from my observations, when an item is picked up, all the faces of the model are made transparent, and when it is able to be picked up again it goes solid. It doesn't reload any information from the model itself. As a guess, I'm sure this is a Blockland error that you should go pester Badspot about, unless there's a callback function that runs when the transparency was set so you could do it manually (if this is even possible).
Actually, I don't think I've ever seen any items in BL with transparency...
You might even be the first person with this problem (or the first to bring it to anyone's attention).
