I'm trying to use the monster cube dropper, but I need it to deploy cubes that walk, these cubes are shivery cube state monsters though. I couldn't seen any difference between it and other monster cube droppers from decompiled maps, what gives?

Did you use cube_dropper_a4?

It could be something in the map properties also, but I highly doubt it.

On the VDC page for prop_monster_box, one property is "start as box." The instance you're using probably has that value set to yes. Just copy the instance, rename it, and then edit the copy so that the value is set to no.

Ah thanks, I just hadn't scroll down far enough in the properties apparently.
