After i saved the farmstead i go see Robb Stark and nothing appears in dialogues...
You probably had another quest open with him?
Yes the one with the Clansmen base... we can't do two same time ?
I had the same (destroy clansmen base) Winter is comming quest worked without any bugs.
I remenber i did the two quest same time in previous version, so i was surpised i couldn't do it this time, i will try with 2.1
