On a Tomb (where is a "dry" well) after passing the force field you have one of the tombstone that can be activate. All characters are saying they can't move it but my dwarf don't trigger this sentence.

So 2 choices my stength is enough but it's bug or the sentence is bug for a dwarf (custom char). By the way if someone has a hint or the answer it will be great.

In this tomb I have found a secret area with a switch but it did nothing it seem.
