Hello, I just discovered gui/gm-editor and it is really fun to experiment with it but I was careless and messed up. I started with some easy stuff like changing attributes and size in arena then I went in fortress mode and tried changing things like preferences. I did not bother making a new fortress to while experimenting,figuring that I just wont save if I crash something so I used my actual fortress. Everything was fine until I tried to change a short sword into a long sword. I did it by changing the sub type. On the surface, I succeeded : it became a long sword in name,attacks,and everything while nothing crashed. Satisfied with the editor for now,I returned to playing my fortress without bothering to restart DF since I didn't do anything important(or so I thought).
But when I tried to load my fortress today,it crashed. The error log said I had duplicate long sword and unrecognized short sword weapon tokens so the entities failed to finalize. I noticed that I could load the save without crash for some reasons if I play in arena for a bit first. From my observations(my forges could make long instead of short swords) so I think I changed the whole short sword(as an type of weapon) to long sword instead of that specific one. Then I tried to undo what I did but ended up breaking both short and long swords as well as mauls. I went into my save raws but everything was fine.
What went wrong? How do I fix this? Help!
