-At lvl 9 basketry, in order, I learned the masters hat, adepts hat, and mentors hat
-At lvl 10 basketry i learned the GrandMaster's hat.
-I learned the twisted rope and braided rope in the same crafting attempt
-I learned the Grass Mat, Grass Thatch , Light Grass Plate and Heavy Grass Plate all in the same crafting attempt
-Having initially had one item or more from each of the masons, scrappers, scavengers, pioneers, gadu, bamati and banaya sets, I leveled up 8 times, from 59 to 67, and only leaned 2 items. A banaya mat floor which uses grass and a masons post which was in game before. I leveled up building several hundred Gadu Branch Barricades.
My stats are; 68str 70for 65agi 68dex 76int 53per 49chr 54spr
IMO, it seems like learning recipes is not functioning correctly.
p.s. architecture was my starting skill
