It seems i have to edit the 'Max Stock', 'Seconds Between Refills' and 'Refill Amount' each wipe, on Bandit vending machines that are added to Outpost to create Combined Outpost (Rust Maps option). Is there any way to save the settings on these machines so I dont have to manuall set each wipe?

I assume they should be saving already. The plugin tracks customizations according to the relative position of the vending machine within the monument. I wonder if the relative position is changing each wipe.
