Oggy,
the issue I had before,(Exeption thrown when trying to modify certain pieces of equipment) I have managed to find reduce the cause down to the Data that comes with 1.6 and 1.6.1. I discovered this by copying the data from 1.5 into the data location of 1.6.1 and when I went to modify the different items it did not have an exception. I haven't figured out witch file in that directory is the cause of the problem yet though.
