This is going to cause massive loss of materials
This is how i replicated it
At clothing table (doesnt matter which, iv done it with bs as well). Selected a lvl 12 chest piece but did not create it. left table and went to bs table, selected CP150 chest. Went back to clothing table its auto selected CP160 gear.
I didnt create anything through this particular run but did earlier and spent a lot of mats before realising it was cp160.
