Do me a favor do a /outputfile recipes poisonmaking and pm me that.
Checked on a rogue with no skill/books learned and the consigned was not there, so not autolearned and should count.
What you also could try, delete the ts directory and reinstall the macro (have seen that windows patch screws up permissions and could not update the dump file, was stuck doing same recipes over and over)
