Guards attack me

[Ke'hl'ash Silinrul]

I made a drow subrace char and used neutral evil alligment.
I joined Shadow Legion faction and after few dialouges enterd the house.
There all guarda and assassin attacked me and killed me over and over. I respawn and they drop me in second. I tried few times to respawn but I was stuck in that room with no chance to even open my inventory.
I think that factions got messed up and they see me as foe.
