------------------------

the issue happened when I finished a metamorph encounter, an organ dropped (maybe it is an eye piece, not sure) and game crushed.

tried to re-enter the zone, same issue happend when I moved into the area where it droped

tried again while disable highligting, it is fine, the moment highligting is enabled, game crushed.

tried again while disable item filter and highlighting, it is fine, the moment highlighting is enabled, game crused.

tried again while enable item filter and highlighting, then pickup item by the filter-lightbeam and mouse-over method, it is fine to pick up 2 catalyst dropped along with. the moment when I mouse-over the organ, game crushed.
--------------------------

I hope this log could help the technical team to pinpoint the issue.
