The Morag Tong "writ" script is a bit wonky. I first went to Andothren, but was told no writs. Directed to Almas Thirr. At Almas Thirr I was first told the same thing - but when I entered into dialogue again with the MT Master, I suddenly had a whole new load of dialogue options, and writs were available. Found this same inconsistency happen quite a few times subsequently.

Can't quite tell whether this is a way to try and distribute the writs out, but it didn't seem to work for me: it was Almas Thirr only that seemed to be dispensing writs.

And on Morag Tong: the writ to assassinate the hiding ex member in the small village SE of Hlan Oek has a bug in the script where you come back to assassinate him: it seems to add his equipment and force greeting, but it loops constantly, therefore by default you can't do anything as it forces greeting, constantly.

Edit: Also in the MT writs: the bandit leader in the Othrensis woods (apologies if not correct spelling!), the tent (interiors) doors are floating.
