I've had non-blocking-saving active since the longest time, always worked.
As of the latest update now every time there's an autosave the entire game freezes until the save it's complete. I checked the secret settings and the option for non-blocking-saving is still on.

The vanilla loaders (which are used as a basis by some mods) do not have a setting to prioritize most or least spoiled items like inserters do.
Would it be possible to add this option?
