Trails In The Sky 2nd Chapter — A Hotfix For Startup With Inactive Monitors
Steam hotfix 1.03.2 addresses startup with an inactive monitor connected, incorrect upscaling effects and language settings on the first launch.
Trails in the Sky 2nd Chapter's Steam hotfix 1.03.2 addresses a startup failure that could occur with an inactive monitor connected. If that matches the setup where the game would not open, update the game before trying again.
The September 18 patch notes describe an occasional failure under that condition. They do not specify affected monitor models or connection types, so the fix should not be treated as an explanation for every launch problem.

Upscaling effects and initial language settings also change
The update corrects certain visual effects that could display incorrectly when upscaling was enabled. The notes report a rendering fix, with no frame-rate improvement claimed.
A third correction addresses language settings that could be wrong when the game was started for the first time. This concerns the initial setting, rather than newly supported languages. All three fixes are listed for the Steam release; the post gives no corresponding console update schedule.
