Melee bug is it?

So the old melee bug,

It drove me up the wall, so with a little reading and learning how to use the PFM, and the suggestions of those capable modders I think I thought I fixed it.

Those suggestions were:

double range for muskets and rifles (done)
change line infantry to light (done)
reduce melee range (done)

Aha, I (they) seem to have cracked it. But loe when the enemy attacks (at whatever section of my lines) some sit back firing volleys while some fire one volley and then assault.

Is this still the bug, or is the Ai attempting to actually attack (?!). Comparing to on some occasions I see the enemy march into range stop and then begin an infantry duel. I just can`t tell. When on the defensive ai does what is says on the label, only in attack do I get assaulted, yeah it seems obvious that in an assault there would be an assault. Maybe I`m only comparing to what I would do in an assault, and that is volley only with cav smashing the lines and then only inf to pour through the hole.

Maybe I`m just chasing my tail.

What do you think. If there are any suggestions as to any other alteration I may include please let me know.
