Same thing happened to me, was using wood frame and was trying to copy shape. Is there any way to fix this without deleting character from server and starting over? I tried killing myself and I'm still stuck alive but my bag is on the ground. If someone attempts to open my bag they get a null error too and can't open containers till the relog.
Code:
IndexOutOfRangeException: Index was outside the bounds of the array.
