Ok, I had recently gotten the Dwarf Spider Droid files and even though it walks and fires it has an animation error. Look at the legs. And in other maps you can walk through it and it can't walk and is completly usless.

That's weird, did you just place it in ZE like an object or did you spawn it from a vehicle spawn and set it up as a walker in your LUA?

Yes I used a vehicle spawn and in the .lua

We're gonna need more info to help you, post what steps you've taken to set up your custom side, show us your LUA, and check your Bfront2.log for any Dwarf spider related errors just to be sure there aren't any.

Edit
Try out this dwarf spider side, it works fine in my map

Ok, thanks Ace! I'll report back soon.

EDIT: It works! Thanks Ace!
