mine was working fine until my computer crashed in the middle of playing, when i tried relaunching the game it kept giving me that error even after verifying integrity and reinstalling. i even tried relaunching it without the patch and it still gave me that error thus safe to say it has nothing to do with patch

Why don't you fix this error?

I emailed the development team, I hope they respond because this is annoying

They still haven't fixed the game. I can't play from the desktop PC and the laptop. I wouldn't expect this from Kagura Games.

Same problem, now I get it why this game is on a huge sale !..

I found same error when my computer crashed in the middle of playing. I don't sure it can help you but I can fixed by Re-install game + patch -> Delete folder SaveData in my computer -> close stream cloud of this game in stream-> It fixed I can play without error now

So i had the same issue but resolved it on my own. The problem is probably with the patch from Kagura games not working right. just extracting it to the main file for the game won't work fully. If you open the En patch folder then open i think the last folder in the list you should see an application start it and it will download everything for the patch. Make sure before you install that the folder selected for where to install is the main game folder. it should be selected automatically.
