Infinite loop: conversation with a lord companion

[tos1]

While talking with a companion who become a lord, the conversation repeated infinitely. I cannot break it with any key, and had to terminate the game using Alt F4 key.

----Lord Bronson Snow
dlga_start:lord_start.6|Yes, my {reg59?Lady:Lord}?
----L
str_comment_we_defeated_a_lord_upstanding
I will not forget our victory over {s54}. Let us once again give thanks to heaven, and pray that we not grow too proud. 
----L
dlga_lord_start:lord_talk.5
What is your bidding?
----Player character
dlga_lord_talk:lord_talk_ask_something
I wish to ask you something.
----L
dlga_lord_talk_ask_something:lord_talk_ask_something_2
Aye? What is it?
----P
dlga_lord_talk_ask_something_2:lord_talk_ask_location ---> (*1)
I want to know the location of someone.
----L
dlga_lord_talk_ask_location:lord_talk_ask_location_2
Very well, I may or may not have an answer for you. About whom do you wish to hear?
----

The player char wrongly says the "I will not forget our victory over..." said by Lord Bronson Snow above. Bronson says "Very well, I may..." again. They repeats infinitely the last sentence each other.

*1  It may be dlga_lady_talk:lord_talk_ask_location.

- How to reproduce it/when/why it happens:
Play as a female character without belonging to any faction, capture at least one castle (to become a Queen), Give a companion a fief (village). I tested Bronson Snow and Ryder. He becomes a lord. Talk to him and select the choice above.

- Game version (and steam or downloaded):
AWoIaF v8.2, Warband v1.174 downloaded

I have done an attempted fix for this for V8.3
