Forget the original game (V1.0.0) and go to the BetterRepack from ScrewThisNoise - uncensored and full modded.
HS2 recent version is R13.

Pls note that the "Optional Sideloader Modpack Studio" (~ 170GB to download) is ONLY for StudioNEO and NOT for the game.
According to the lot of desperate members having troubles to get the game installed with splitted files (read 1 page above) I strongly recommend torrent download.
