Yup there is a direct bug within the code. It should be 100 instead of the 300 as written. It is with the Bandit version of the quest (the other version doesn't have this error).

Under that premise, when I take the bow option I should get 200 more gold.

The loot for the encounter may be set separately and the encounter itself can give you 200 gold, hence it is still an error, since they can do the appropriate feedback to the player. That is a simple change as well.

Fixed, thanks.
