I was able to fix the problem
It turns out that Slof's BB just need resources i think because i didn't merge or bash or anything i didn't even put in the esp's of Robert's male or female and it worked fine
Before i did that i removed Slof's BB and EVE fix and Roberts male and female and i replaced COBL_races and COBL_races - Balanced with the ones i had in COBL v171 folder
Then i tried the game without anything and i had no problems
Then i merged Slof's BB and it still worked they had wiskers and nails
Then i merged Robert's Female and after that i merged Robert's Male and it seems to be working for now... I hope everything is working fine
However is there a way to avoid that fingernail from Khajiit trough the boots or any footware well it doesn't really matter...
And one more thing Corepc i wanna ask you a few questions....
And everyone thanks for your help

PS. i didn't download the newest Wrye Bash
