Trugg's Troggheads is a Regiment of Renown for Gloomspite Gitz (Age of Sigmar) that should make all Troggoth units Battleline. Selecting it on Battlescribe, however, just hides every not-Troggoth unit from the army list and doesn't move them to Battleline, thus making impossible to build a proper army list without the Roster Errors notify popping up because there are no Battleline units.
