Amon Hen Boss bug? (spoiler)

[Breoc]

Got to the orc boss on Amon Hen. Post hobbits being taken. I get him down 2 hearts and then he goes immune to all damage and doesn't continue the fight. Am I alone on this one? I'm going to try it again tomorrow, but thought I would ask before banging my head against the wall.

Restarted the level and my auto save put me right at the boss. Was easily able to defeat bug free.

This happened to me a few times, I couldn't find any info online about it so I'm glad it wasn't just me. But same - restarted, and the third time managed to get through without the bug.

Seems to happen more if you keep thrashing at him with the sword when he collects the shield...I made sure to hit him once, then run away, to get through it.
