Hi Jemilly,
I have a plan.. I will make it so that you can unlock anything that is in a room/location YOU created.
This way you will be in complete control of your world and noone can leave locked objects in it without your permission.
I will let you know when I have done this (it will probably be in version 5.03) which may be several days away.
A QUICK FIX until then is to do this:
create a box
put the unwanted object on the box
put the box on the unwanted object
This will hide both the box and the unwanted object.
have fun until then.. and have a wonderful easter too!!
