BioWare Warns Against Making Custom Changes to SWTOR Loading Screen
In a recent post to the SWTOR forums, Associate Online Community Manager Joveth Gonzalez warned fans that if they make the changes, they do so at their own peril.
Weve noticed that many of you have been going into your SWTOR game files and overwriting the default loading screen. While this has resulted in some very impressive custom loading screens, we need to remind you all that changing game files will corrupt your installation and force you to repair with the subsequent patch.
Overwrite your SWTOR loading screen at your own peril.
