* EQUI_Animations.xml file
This shows as having been updated. What happened (and you can follow the progression if you check the threads in the Test Server forum) is that originally when creating the Target Con box, they had put the definition for it in the Animations file. In their process of tweaking based on feedback they received, they subsequently took it back out of the Animations file and put it directly into the Target Window. Hence, no actual permanent change to the Animations file. In other words ... forget about it, you don't need to make any changes to your custom one.
** TargetIndicator.ini and TargetIndicator.tga
It is my understanding (I haven't verified this as of yet) is that if you wish to have the Target Indicator ring show up around your target, you need to copy these files into your custom UI folder.
Should either of those statements (re Animations or TargetIndicator) be incorrect, feel free to let me know so I can change this accordingly.
