So the snow where I keep turning off the power and I'm wondering if it possible to make autosave to do it more often (like 3m) and for snapping is it possible to turn it off when placing benches and bins? Thank you
There isn't an option in-game for altering the autosave interval. Some (including me) have altered it by editing one of the config files, but I do not recommend doing that as it may have unintended effects.
In terms of the snapping, have a look at the bottom right of the screen when placing path items.
