Where does yGather save its data?
The yGather data is saved in the file "Runes of Magic\SaveVariables.lua" in your user directory. (not in "Programes\Runes of Magic") It can be edited with any text editor.
Look for a line starting with
yGather_data = {
This line and everything that follows up to the line that starts with (and only contains) a not indented closing brace is the yGather database.
