Description of Bug Experienced:

When being Large and using a two handed weapon in one hand, even if you're not holding something in the other hand AND not using the -twohand command, you do not get the weave AC.

Steps to reproduce the Bug:
Be a firbolg and spellsword.
Put a greatsword in one hand.

Expected Result:
+ ac from weave ac

Actual Result:
Nothing (at least on chara sheet).

There should be some indication of receiving the AC in your combat log whenever you equip/unequip a weapon. I -believe- it's supposed to show up on your character sheet as well, though. I think it'd help if you could screencap that log.

So:

When I login with no weapon equipped: I have 15 AC (weave AC counts, as shown in first screenshot)
When I equip a two handed sword with nothing in offhand, it automatically activates -twohand, so it by design turns off my weave AC, not a bug.
When i desactivate -twohand, weave AC doesn't come back. THIS IS THE BUG (as shown in second screenshot). The console gives me the "I have something in my offhand" message even if I don't.

I also had this issue when I played a firbolg when they were initially released. IIRC a developer told me due to how NWN assumed no one would and/or could play a large race, so it assumes you're holding the large weapon with both hands. It's why large races can't wield two large weapons, either.

IF not fixable I would suggest adding it to the wiki as a forewarning that it is not compatible with Large creatures holding two-h weapons.
