15 year old character not done with CoP?
Anyways, the likelyhood or getting any quick response from SE is minuscule at best.
Plenty of people have offered specific ways to try to fix the problem yourself which is highly recommended.
If you are worried about using a 3rd party tool or have a certain disdain for 3rd party tools, below are some thought provoking statements:
1. Ffxiah.com is a 3rd party tool
2. My character uses many of the tools mentioned previously and has not gotten banned or jailed
My suggestion, get windower and tako and just fix this yourself.
With all that being said, it sounds like you are extremely adverse to any sort of risk. My first thought would have been to try to fix this myself.
Another thought: The vanilla version of FFXI is 15 years old. Think of Windower as "Mod Organizer" for FFXI, and the addons for Windower as mods for FFXI. If you play Skyrim, chances are you either use or have heard of Mod Organizer and certain mods, like the Unofficial Skyrim Patch, that can fix certain hiccups in Skyrim's coding that Bethesda is just TOO *** LAZY TO FIX. Likewise, SE is too *** lazy to update, add anything useful, or release bug fixes for FFXI seeing as how it's a fifteen year old game.
