This issue triggers when some data is missing. Why? Because 2 big (as my c) reasons:I am on the steam version with dlc, and whenever I download the mod (1.6.4) and I try to play the game, I get messages that say files cannot be found, so certain sounds or images just dont work. Does anyone know why this happens?
The first one is simple: The game wants file called "imouto_some" and the mod has got "inouto_some". Mod creator's fault, you can tell it here and the mod will be fixed.
The second one is simply the non existed game files that can be caused for a bad installation OR because you unzziped the mod with a software who made some mistakes. The OS has got a unzipper, try to not use it. Use 7zip or WinRAR.
