Ignore list?
 

_Skinnable_WindowElementsMini.xml is on IgnoreList, not updated.
Where is the ignorelist and how i can change that?

eq2map_ignorelist.xml is the file in your custom UI folder.

You would just have to remove the line that includes the file you listed above.

Might be worth mentioning that whichever mod you have that placed that file on the ignore list likely did so with a reason. ;)
