Equiping previous armor when using spell

[kokono23]

When I use a spell (I have only seen it with destruction spells), my current armor gets unequipped and somehow the armor (that I didn't even had in my inventory) I was previously wearing got re-equipped. I have never seen this problem before on my 50+ hours character. I had around 150 mods. Now I have a completely different mod setup and it still happens.

 

The only thing that both profiles had was a Wrye Bash patch for the leveled list and that was the latest mod that I had on my old profile.

 

Have other people experienced this problem with Wrye Bash or could this be something else?

 

Edit: I should also note that I updated to the latest version of SkyUI and that mod uses groups to equip armor sets, but I don't use the favorites menu from SkyUI and I have never enabled a group.

 

Edit 2: error log that I found:

Found out that version 3 of Wrath of Nature is bugged. That mod is somehow causing this.
