Can you send me a save with this error at redikalsoftware@gmail.com please. Would like to take a look.
Open the game folder, you will find a folder named "saves", you will see a number indicating page and position, for example for a page 1 save 8, it will be page 1-8-LT1.save. If you don't know exactly, can take the full page of saves where the savefile with the bug is located and send it to me by email in a .zip.
