Lots of "invalid escape sequence" in regex sequences not prefixed with r on python 3.12

[RegentOfOrigin]

All scripts that contain regexes not prefixed with the r character complain aboutSyntaxWarning: invalid escape sequence XX for all escape sequences. Can be simply resolved by throwing an r in front of the strings (used on some sequences but not all).

Easiest way I found was to do a search for:
re.search
re.sub
compile

And I think that caught all the instances?
