I am trying to walk out onto the beach towards the Lighthouse outside Cyseal.

Problem is, everytime I do I step on a mine and my whole party dies.

Funny thing is, I noticed the mines were visible before I walked out onto the beach, but once I got close, they vanished. There seems to be no way to search for them, meaning the way is totally impassable.

Is there a way to search? Is it a bug that they were once visible and have now vanished?

Thanks
