Welp, I did as you instructed, but nothing has changed. I even made sure the AppData file was not read-only, and even made the specific Paradise Lust file NOT read-only in case that did something. Nothing. The game is still freaking out like crazy.
I decided to delete the Paradise Lust file, as said before, I don't mind starting anew. However, that didn't help any. It seemed to help, at first, as I no longer had the Quest Tab pop up during the start of the game, but once in the game, when I accessed it, it clearly was still fucky. Inventory too, is flashy as all hell!
I checked the log, and although no genius in coding, I found those lines.
The referenced script (paradise.ToolSet) on this Behaviour is missing!
The referenced script on this Behaviour (Game Object 'Tools') is missing!
By this point, I feel like this issue, if I am not the only one having it, needs some serious looking into. Cuz, as said, I did not re-install my windows, but did have updates. Perhaps one such update caused this? But if so, wouldn't that mean other people might run into this issue as well?
