Bug in chapter 5 with burning tower, can't progress

I'm playing the game on the PS4. I'm in the part of the chapter where you have to cross the battlefield, where the chain on a burning tower needs to be broken with a stone to drop down the dead bodies and allow the characters to cross (I've checked playthroughs online).

When I do it, there seems to be a glitch. The chain breaks, but the bodies don't drop down.

I can't progress to the next area until this mechanism is fixed! Anyone else facing this problem or have a workaround?

I am having almost the same problem. I am on the Xbox 1 and I can not even see the cross airs to hit the chain to bring down the bridge. I have restarted the game and nothing!!!
