Terra Invicta PowerShell save editor

SaveEditor.ps1

# Quick save editor for Terra Invicta in PowerShell
# Released under MIT license by <Superflue@github>
# Use PowerShell ISE or VSCode to more easily tweak stuff.
# Just place a breakpoint (F9) on the line pointed out at the bottom of the script
# And then you can use the examples in the if statement as a start
# This script handles the compressed saves (gzip)

# For simplicity we just hardcode the name of the save to edit (just call it "editsave")
# And the output is called "modifiedsave"
# This is just a simple way to avoid accidentally breaking an important save
