Bug in chapter 4 running to the boat PS4

I can't join the boat at the end of the chapter 4 after inflame the mill because there are mountains of rats running much more faster than me. I tried hundreds times. I think there is a bug, someone can help me?

I'm also having the same glitch but on Xbox One, I try to get to the boat but Amicia and Lucas get outpaced by the rats and swarmed, it's really annoying and prevents progress.
