Improved horns of Valhalla - inconsistencies with Readme

[Onox]

Hello,

I was wondering whether the Improved horns of Valhalla mod does not have a few problems ? It seems that the armor the berserker is wearing is not correct with the Bronze and Iron horns. According to the Readme, it should be a Hide armor +1 (Silver)/+2 (Bronze)/+3 (Iron), but in the game I tried adding the summoned warrior with Ctrl + Q, and he only has a basic non-magical Hide armor with the three horns. The +2 disadvantage to AC stated by the Readme also seems to be -2 bonus in the game. For example, with the Iron horn, the berserker has the following AC :

Hide Armor
Armor Class : 6
Dexterity : -4 (18 Dex with Iron horn)
: -2 (with no left part, I think this was supposed to be the +2 disadvantage)
Armor Class Modifiers
Missile : +2
Piercing : +2

Total : AC = 0

But I would have expected : 6 - 3 - 4 + 2 = 1

Maybe I'm just completely wrong, tell me

Furthermore, the installer still says it's version 1.2 instead of 1.3 :

[C:\Program Files (x86)\Baldur's Gate II Enhanced Edition\Data\00783\setup-ValHorn.exe] WeiDU version 23900

nstall, or [N]ot Install or [Q]uit?
