Objects placed in large instances will disappear after moving regions (hitting a load screen between two regions) due to the way instances have to save locations. The objects will reappear if the regions you have loaded exactly match the regions that were loaded when you initially placed the object.
For example, in floor 1 of Hallowed Sepulchre, if you enter by the SW entry and place objects, those objects will persist if you enter again (load the area again) by entering the SW entry in a later run. However, entering by the SE entry won't render those objects because the regions loaded at one time will differ.
This is only problematic in instances that are large enough to have loading screens when moving between regions in that same instance. There is no known fix for this at this time.
