Prevent lack of DDLC game files being bypassed by pressing "Ignore"

[initializesahib]

Essentially, attempting to launch the mod without the base game's files results in a Ren'Py error screen. If you click the "Ignore" button, the screen will be bypassed and the mod can be played as normal.

I've just replaced that screen with a more fitting one that doesn't allow for a bypass.

at the moment after hitting ignore it just appends the regular disclaimer to that one which is kinda funny actually

Perfecto.
