I noticed that in secondary products of various letter decompilations there is no letter "D" as secondary product.
I know letter "Z" is an "End Game" letter thus it's unavailable as a side product of decompiling any other letter.
But letter "D" is also not on any secondary products of any letter.

I'm just wondering if it's intentional? If not there are many secondary products of letter "I" and "D" could take one of those places :P

I'm just curious if it's intentional. If yes then I'll just beeline Solid Fuel to get "D"

Before you have access to CRUDE OIL BARRELs or SOLID FUEL for infinite D production, you can get Ds from decompiling WOOD (or BURNER LETTER DECOMPILERs), which gives a temporary, disposible source ^w^

so i'am about 10 hours in and for the life of me i can't figure out where to get a V from. i'm trying to build a locomotive to make getting to and from the oil field automated. edit never mind, its stuck behind heavy oil
