Insufficient Modified Tumble AC Penalty applied twice.

[zDark Shadowz]

Hello, I'm currently playing a level 7 Barbarian who has 5 ranks cross-classed into Tumble.

I have insufficient tumble at the moment to keep it at 5 and above, so when I equip my full plate I have a -1 AC penalty applied.

However, when I equip my large shield I get penalized a further -1 AC. Unequipping the shield still leaves me with a total of -2 AC penalty.

This bug persists until I unequip and re-equip my full plate, however this isn't a real fix for me as I frequently switch between a greatsword and a longshield/large depending on the situation during combat, which causes the bug to resume once more.

Thanks for your time.
