Tested various combinations of enabling or setting things to 'More', as well as both random algorithms, got multiple errors relating to wooden chests, including "Failed to load mods: Error while loading item prototype "wooden-chest" (item): Must have a fuel_value when fuel_acceleration_multiplier, fuel_top_speed_multiplier, fuel_emissions_multiplier, or fuel_glow_color are used." as well as the 'error()' function on line 512 in flow-cost.lua logging the wooden chest as being unreachable after it's cost was changed. Also had 'old_amount' in numerical/recipes.lua be nil several times. Of note is the wooden chest in K2SO is unlocked by default like in the vanilla game. Would it be possible to add a recipe and/or item blacklist, to prevent the randomizer from changing or considering those items/recipes?

Edit: Upon further testing (adding the problem recipes to the 'sensitive recipes' list), it appears to have issues with any recipe that uses wood, which includes but is not limited to small power poles and K2's recipe for green circuits that uses wood instead of stone plates.

That's a great idea; I've been wanting to add a blacklist for a while but so far have had more pressing things. I'm working on some new algorithms and am partly hoping they simply won't have those issues, though I might have to go back and fix recipe.lua properly if things don't work out.
