@Claus,
I was thinking since the members of the data structure only exist during runtime that maybe they should be saved to a file. I found similar in aum 83 and aum 69. If they were saved to like a *.ini file then they could be read anytime and none of the information would be lost. The thing is that your template is alot of code and every instance would have to be found and then read from a file.

I'm still at the artwork stage of my game and unfortunately I dont have the time to help.
