I rezzed the object, shrunk it, and took it again.
I tried to attach the object to right forearm, but it attached to pelvis.
I detached it and tried to attach it to a different location, but it still attached to the pelvis.
The problem does not occur in 1.19.0(5), I attached it to my right foot.
However, when i went back to First Look, the object would not attach to any place except right foot.
It is an invisibility prim (if that helps.)
