Did the game patched or why you think an update is required?
They pushed an update a few days ago that fixed some minor graphical bugs and a few weird freezes when doing certain specific action combinations. The only files updated were several FMV files and some of the asset files. The game executable and its launcher were not touched.
I personally tested the trainer and all of its primary functions except the jump rope (didn't have a save at that spot in the game) as well as trying to edit several values in the editor. All functions worked the same for me after the "update" as before and I had no problems editing any values. I did not try editing the game time, though from what I understand that one was finicky for a lot of people in the first place.
