I´m glad you still use the Ore Classes (makes my refineries happy ^^ )
With the Survival update the definition of some classes have been removed -
EnergeticIngots,Solids and PreciousMetals to be exact.
It doesnt seem to have any impact if the BlueprintClassDefinitions are there or not, but maybe you still want to add them back in.
I´m just posting this as a "heads up" and with the missing stuff below (ignore/delete the "BasicMetals" if you dont find them useful - also aplicable to my whole post ;) ) so you wont have to dig it out of the pre-survival files.

I readded them (plus the extra class for arc furnance ores ) in my refinery "mod", and will try to maintain a seperate patch file within for your ores that would/could be used in the arc furnace.

<!--NEW and optional Class "BasicMetals" below
I (Schattensonner)added it to seperate the Arc Furnace Ores.
Survival update changed the "CommonMetals" to fit the Basic Refinery and now includes Silicon,Magnesium and Stone.
Obviously this class is pointless w/o using my or any other Refinery mod that utilizes it.
