Interesting, yeah it is the image effects, but I'll try to fix it for the next update. What device are you playing on?

I see, this has also happened for another player who reported on Discord, they also happened to get this issue on a Windows computer! Although, I personally develop the game on a Windows 11 computer as well, and it doesn't occur for me.
Like I said, I will see how I can resolve the issue, but in the meantime, reduce the graphics quality to medium, disable the image effects, and then try again.
