Collectible Card Game Headquarters

Describe the Bug:
The assembly-workers generated by Urza's Factory use the animated Mishra's Factory template. This means that if you view details on them, it will show them as having Mishra's Factory abilities (although they don't actually seem to get them.) Additionally, they appear to count as land, at least to the extent that they stack with your other lands when autosorting your field, instead of with your creatures where they belong.

Which card did behave improperly ?
Urza's Factory

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
KOT, duel

What exactly should be the correct behavior/interaction ?
Urza's Factory should produce generic 2/2 Assembly-Worker creatures with no abilities that are treated like normal generic artifact creatures; mechanically, they don't actually have anything to do with Mishra's Factory aside from the name (and therefore the ability to be pumped by that card.) In particular, they shouldn't count as or stack with your lands, and shouldn't show Mishra's Factory abilities when examining them.

Are any other cards possibly affected by this bug ?
No idea.

This has already been discussed by Devs here:

and got probably stuck by Korath's last response to the problems that will be caused by giving it a new csv ID + Korath is absent since then unfortunately.
