Changing Actor?

When the Einsatzkommando come to arrest Glaeken, one of the guys keeps changing. He's played by a short and thin unidentified actor when seen behind Wolf Kahler in the inn, and armed with an MP28, but once they get outside, he's suddenly bulked up to the beefier uncredited stuntman Doug Robinson and is now armed with a K98. After the sequence of Glaeken being shot, he changes back to the first unidentified actor when the six remaining Nazis go back inside the keep, but he's got Doug Robinson's K98 instead of the MP28 he had at the inn.

All I can figure is they couldn't get one actor or the other for both interior and exterior shots, and hoped nobody would notice (I certainly didn't until by chance I noticed he seemed shorter in the interior scenes than he was in the exterior ones). As for the changing weapon, I think that's just a goof.

It just bugs me because I've checked, and all six of the other Nazis in the sequence are played by the same actors/stuntmen throughout the sequence, and their guns remain consistent, but for some reason, Michael Mann seemed to be having problems with the seventh Nazi.
