A level 1 Zen Archer gets one bonus feat drawn from the Zen Archer bonus feat list.
The current data autobuild has a special "zen archer bonus feat" category, but all of the feats in question require "var: MonkBonusFeatLVL at least 1," which Zen Archer does not receive; thus no bonus feat can be selected.
(Apologies if I got the priority wrong; there's no easy workaround, and this makes the Zen Archer archetype more or less unplayable..)
Priority is set by how it affects the whole system. Investigating this now.
Thanks for fixing this for Zen Archer. It looks like it also applies to Flowing Monk; I'm guessing it's going to apply to all the monk archetypes. Would you like me to open a new ticket?
Yes please, new issue or problem discovered = new ticket.
