I just added the Tunneling Jaws upgrade to the Baneling, but it behaves in an extremely weird fashion. I tried everything: applying Tunneling Jaws to Roaches - it works, showing that the problem is not the upgrade; compared Roach (Burrowed) and Baneling (Burrowed) data and found no differencies in Movers, Acceleration or Rotation; there are no weird effects nor behavior nor triggers nor other abilities involved; also checked if the problem persists in an online game - it does... I really don't know what's wrong.
I finally managed to fix it. It seems the cause was not having Acceleration set to 1000 on the unit by default, despite it was set to that value by the upgrade.

I'm baffled, but I'd like to see the map itself.
