Thanks for the tips. I've read some pages of the installation guide, and decided to try restart all over again.
I've unistalled everything and tried only the basics. And for my surprise, it worked perfect! Above the only plugins I'm using.
Now I'll try to install the other dozens of mods (cloths, armours, furmitures, creatures, quests, folowers, etc ), but just a few at each time, and testing animatyion and other things, to try to discover which is the mod that is messing with the game.
But I have a question: can we use the "loot" plugin to sort the mods? I was working fine with SOS, and I hope I can contiue to use it.
I'll post here the progression if you don't guys don't mind. kkkk
