Bug in funerary room ? (Highlands Park and Dolyn Ice Wall access)

[Vinssou06]

hi all!

I'm blocked on the funerary room, after defeated the zombie viking boss and got the fire elemental pet. He's supposed to melt ice walls ans ice ennemy's, and that's it's ok, and I get the new shield like this.

But in front of the ice wall where Dolyn is (and the rest of the game^^), the ice wall didn't melt, and i don't know why... i made the level since several hours and i'm ask me if it's a bug or if i forget something... ?

Please help lol (hope my english is correct)
