Something weird I noticed: if you have items in a crating object (tinkering kit, portastill, etc.) when you save, the exit steam, they will move into different places. There doesn't seem to be any order to where the items move. If an item is moved into a lutefisk cube, it won't be turned into lutefisk, but instead any more items put into the lutefisk cube will turn into what's already there, meaning that a lucky player could have an easy method of duplicating a very powerful item.
As an example, the time I discovered this was when a bolt of mass destruction ended up in the lutefisk cube. Adding a wooden sword to the cube resulted in another bolt of mass destruction. This is a huge problem, as ANY item can be duplicated this way.
