The term OOC regen is usually found in MMORPG but it's basically the same thing here. Anyway, it's just a name.
=======================================
What the script does:
In vanilla X3 ships sometimes have their shields recharged instantly when docking at a ship or station.
This undocumented feature is pretty inconsistent, depending on things like you personally flying the ship or not and/or the ship being OOS or not.
In short, it sometimes works.
This script does it everytime. Every one of your ships.
A ship docks, shields are full. Simple.
=======================================
Techy stuff:
This is an AL-plugin.
Note that it can take up to 5 min for this feature to activate on a newly acquired ship.

Installation: Copy all 3 files into the scripts folder.
Deinstallation:
1. Turn the script off in the AL settings menu,
2. then delete those 3 files from the script folder.
Turning the AL-plugin off will also stop all running OOCR-scripts on your ships.
The CPU usage is then basically zero.
