Nice catch, pushing this through for Nano.

Yeah makes sense, I think the way these two units were made was copying the Arcanist unit and replacing the model, animation and texture as well as tweaking a few other details. As they're survival units not much though was put into what that would mean outside of combat.

On the other hand, the chunder one in particular is hilarious.

Hah that's great. Because the Dwarf rig has a work animation I suspect that is playing when the Dwarven Arcanist researches, of course the Warden works in the Foundry so the work animation is built for that. Rather amusing side effect.
