Cannot execute command. Error:[string "for i, force in pairs(game.forces) do..."]:24: attempt to index field 'tungsten-boxing' (a nil value)

This is on the experimental branch.

this is on an existing save but still fairly early in the game and I don't have tungsten researched as of yet.

I removed lines 24-34 of offending file for now and everything seems peachy but that's just a hack fix :P
