Thank you for your help

I did everything exactly according to the guide on how to roll back the version of the game, installed it, as a result, the bug with the first puzzle still does not work, perhaps this is due to the fact that the new version of the game came out with the game where the wall was fixed at the beginning?(

Thanks for helping

can you tell me where to find the tutorial? I can not find

I don't understand how to rollback ppt 2 to the one where you can pass the time on the puzzle, as well as exploit other bugs
