First things first, let's make sure we're on the same page here. I will provide to you screenshots to make it easier. Simply, what we want to do is to rollback to a backup version of the game.

Step 1 : Go to your library.

Step 2 : Right click Wish game and select "Properties".

Step 3 : Go to "BETAS" tab and select the "Backup" instead of "None".

By this point, you should have done it, congrats! Now, wait a bit, give it time to finish the "update" which is basically a rollback/backup version of the game. Once it is done, simply, hit "PLAY" and launch the game normally, select your save file or make a new one, it doesn't matter but just go with your main save file and fight against Erica. If you have the DLCs but you see them locked and can't access them do NOT panic, this is normal because it's a previous version prior the DLCs' release. Nothing bad is happening, it is normal, and I will explain to you below how to fix that back once you done with Erica. Just keep fighting her until you get the two achievements from her, "Erica's True Form" and "Maid or Knight". After you done that and you got your achievements, it is time to roll forward now and back to the current version of the game. Simply, follow all the same exact steps again, but this time on the step 3, change the "Backup" to "None" again and let the game update.

(Extra) Step 4 : In case you have issues with small screen on Fullscreen/Windowed Modes, then simply when you run the launcher, select the resolution of the game, click select a different resolution, then select it again and pick the one you prefer for fullscreen and for windowed, simply uncheck and re-check the windowed checkbox and hit "Play!"

And that's it! You did it! Make sure to thank the user "crimson1117" for providing us with the info of how to unlock the achievements in the discussion of the game's page.


My reason for creating this guide? To help other players with the achievement problem. I assumed if there was a guide about that here, it would make the lives of everyone easier. The original user's post was on the second page and far back lost in other posts, I bumped it so it can go on the front page but I also made a post about it and now I made this guide so it can help anyone else who is struggling with these two achievements. This is a temporary solution as the developers will update and fix the game eventually so this guide might as well become obsolete, still I believe it might help out someone.
