That's weird. Just checked it myself and found that official patch notes on legacy.lineage2 does not include these changes but ru official freya patch notes does.
It's not really a bug - That's how it was made in original game. It was the Freya update where NC soft finaly added unique look to DC/Nightmare sets on kamael. U can check patch notes
yeah I found it and changed already. But here is another question - launcher want to update that eddited file back so I have to launch trough l2.exe is it ok with server rules?
I remember in good ol days u could add UseFullScreen=falseUseWindowFrame=False to the l2.ini and options.ini but now I can't even find l2.ini can I have borderless window on your server somehow?
