Loader code problem?
Check the default template. Go to subscreen editor and click any active subscreen. Look at the Arrow item. Beside it should be a bow, but instead it is a potion. (All quests had been affected...)
This problem might had caused with this change made by DarkDragon:
* - To realize the above, I had to add two "decorative" item classes, "Letter or Potion" and "Bow and Arrow", to deal with the way these combined items are currently hacked into the item system. You can use them in the subscreen as before, but no actual items are members of these classes.
Please make sure the item class is Bows in all active subscreens. If it is not the loader code, you can update the template and all proposed quests but you will have to get backwards-compatibility to older quests... But I believe it is the loader code.
