Please help! Recently, I had started the Thieves Guild quest line in Skyrim. Just now, I completed "Speaking with silence" and after I talked to Karliah she just went back into Snow Veil Sanctum and stays there. I remember that I got The calmer translation for Enthir or whatever his name is, and now the quest line is bugged and I can't do it. (Keep in mind that I dropped Mercer's plans back on the table and Chillrend in its case) I am not sure if Bethesda can alter players in Skyrim, but it would be a godsend. Thank you

Head to the thieves guild, see if anything happens.
