Farming Fungal Grotto I... the room where you fight the boss and put the head on the spike... to the right of the cave opening to take you into the next room, a chest spawns there pretty regularly. And quite often, party members cannot open that chest. Some can, some can't. I'm usually in the "cannot" open group.
I believe something texture wise is blocking movement of certain character types... I think character size/race might come into play here.
