Some kind of minor bug I assume. I also moved the 2nd char they had with them to the far side to minimize the chance of them blocking anything wink

Dropping and picking up worked but only with Scarlett, nothing would fix Roderick so I just had Scarlett place both pendants and I got through....but this is something they got to fix.
