Looked in several places, but there were no signs apparent. However, the streamer was not able to check the table saw as it is very deep in one of the skill trees that none of the players are actively speccing into. It should be a basic recipe, not one requiring lvl 20+ to make a sign. Have they been moved to a schematic? This is one recipe that NEEDS to be available without schematic or any table. It has no effect on game difficulty, XP or skills. All they do is help with organization between characters in the same base. Not game breaking in the least.
