I had special logic running for the class because of the way the class changes BAB. Then LW made changes over the last year to how weapons/BAB work so could be a conflict going on.
Will have to look into this. Don't know off the top of my head...
I've actually identified it after I posted this last night. Before the recent released I had been trying to figure out a lot of this on my own anyway, and Deadly Strikes was one of the things I couldn't get my head around, but the special BAB effect was another, so I poked through the scripts to see what you did.
This still could be the result of their changes, but I noticed you have the script for the improved BAB on the base class, and also had it on the semi-hidden "Fighting Style (Unarmed)". As a test I removed the script from the Fighting Style (Unarmed) entry, and with either Unfettered Kata or Fighting Style with an appropriate weapon training selected (such as Monk, Natural, etc) it properly gets the BAB increase, so that script in the Fighting Style (Unarmed) has been rendered unneeded by something.
The script below is still needed, but, again as a test, I moved it directly to Unfettered Kata entry, and removed the bootstrap for "Fighting Style (Unarmed), and Unarmed Strike is properly getting the extra BAB entries.
Code:
~ Set weapon proficency to the hero &
perform hero.pushtags[WepProf.?]
~ Set Talented Monk Attack Bonus tag to our Unarmed Strike
perform hero.childfound[wUnarmed].assign[wSpecial.RGTalMnkAB]
Style Master is my current Mt. Everest.
