There are still some issues on the updated Editor. Like adjusting backpack inventory count doesn't save when you exit the game like it did before. Ergo, you constantly need the Editor active in the background to have more than the default inventory size. Also the game crashes sometimes upon activating the Editor in the main menu.
I activate the Editor first. After adjusting the backpack slots, I normally close the Editor and then activate the Trainer. The backpack size then sticks until the game is exited. Ax
