Okay nvm, I found a solution to this myself.
There are 2 Seirs only one of whom you can interact with, so manually click on the correct Seir with your mouse cursor. If you get the correct one you will be able continue.
Issue Fixed, I believe this can be used in any other instance where there are multiple characters superimposing one another.
Hope this help to anyone there.
I am unable to talk to Seir after killing Samuel. Also there are two Seirs superimposing one another. I tried restarting my game multiple times, but its giving me the same issue. Please help fix this. I am unable to progress because of this.
Thank you its working now. 
I just tried to log in to shen server after the game crashed, but it didn't show any servers even after refreshing, but after restarting the game via client it is telling me that the server is currently not available when I try to enter Shen server. Rest can be accessed. Why is this?
Please help,
