Current version is Version 12.1 – February 17, 2019, which was when I updated it for the 2/20 patch day. It has been tested and does load correctly. Mainly the inventory window is what changed.
The player window is really just a little rectangle that houses the attack animation/rest/parcel icons.
The group window is a group window that combines bars/stats.
The target window has the target bar/name with the hott target/name & buff icons at the top that is resizable on the top to pull upward.
