Can't get special weapons from lords (valyrian steel etc) (Script Error 131072)

[Daddy]

Whenever I execute or send a lord to the wall, if they have a special weapon (valyrian steel for example) I do not recieve it. I get a message reading (Script Error: Invalid Item modifier ID: 131072
I have tried making a brand new character. I tried being a king, lord and neither to see if the "kingdom" state makes a difference on the outcome, it didn't. I haven't had this problem in earlier versions.
If any other information is needed then just let me know, I wanna get this fixed as badly as you do. Thanks in advance, you're awesome.
