I just got my character to lvl 2 using one level of rogue and then one level of monk. I got a +4 dex mod and a +4 wis mod, and at first I was showing a ac of 18 during a battle (I may have had a bonus included I didn't see), but now it is only showing 17ac. No significance encumberance to speak of (aka holding 11lbs total) and my dex bonus is showing +4 to my ac, the bug is the Wisdom AC bonus is only showing +3 to my ac yet I got a +4 wisdom modifier. There should be nothing to cause this kind of effect.
