Tournament arises when tried a feast despite insufficient money

[tos1]

The feast at a castle costs 1000 stags. When I have less than 1000 stags in possession and select feast from castle menu, a menu with only one choice "Join the Competitions" appears in the left side. This seem to occur always as far as I tried.

- How to reproduce it/when/why it happens:
Own your castle, move or use the money in possession (other than the treasury) so that it < 1000 stags, visit your castle, select "Prepare a feast for your men". A menu appears and the only choice that the player can do is to select "Join the Competitions". This does not occur when the player character has sufficient money.

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

"Competitions" only in the city "Other activities" menu
(The menu displayed in this case of city has some choices other than competition. The trigger is not "Other activities" but "Visit the Inn". Sometimes it occurs unlike the feast at a castle.)
