Possibly a bug found in HC Deadmines

Something very weird happened to my group while doing HC Deadmines inferno earlier.

When entering the room with the spinning electric rods (during the event on the way to Vanessa VanCleef), one of the rods towards the end of the room was completely still, seemingly locked in place, blocking the entire path that you are supposed to cross. My initial reaction was that it was a visual bug (perhaps to do with the new HD-textures, that I have downloaded but turned off, for information). But we all took damage when crossing this roadblocking rod, and died before we could react. Our paladin was quick on his hands though and bubbled through it, and mass ressed us all on the other end of it, and we finished the dungeon like usual.

Has anyone else experienced this before? It’s a first for me, never seen this before, neither in OG Cata or in Cata classic. So I’m thinking this might be a new thing?

Interesting and while I’ve not experienced this exact bug. The cataclysm classic is full of bugs, which the devs seem to ignore.

Amazing aid from blizzard isnt?
