Was curious if maybe you meant to have space age as a required dependency? You get the following error if you try to start it without it.

Failed to load mods: learning-by-doing/data-updates.lua:7: attempt to index local 'tech' (a nil value)
stack traceback:
learning-by-doing/data-updates.lua:7: in function 'update_tech'
learning-by-doing/data-updates.lua:275: in main chunk

Oh my bad, there should have been checks to only modify techs that actually exist but I had disabled them to test if I had miswritten any ids.

As of 0.1.2 the error is now

Failed to load mods: Error in assignID: quality with name 'uncommon' does not exist.
