First line of the ALL_DATA spreadsheet should have a warning not to edit it.

[CaelCoruscare]

When writing to the ALL_DATA spreadsheet, if it does not exist, WildSort creates it. You can find this in ReportBuilder.py

The first line of the spreadsheet should say something along the lines of "This file should not be edited. If you want to access the data, use [Save As] to create a copy."
