Completing the poison harvest quest for Hugh should give +1 to reputation, and rescuing the parents +2. It seems the pause is taking 5 off your reputation for some reason.
If you solve both quests do you get the drop each time? If it is a one time drop you can probably just ignore it (there is no way to edit reputation, that I know of), but if every quest starts giving 5 less reputation that it is suppose to, that may cause problems.
Reputation-list-spoilerTry deleting all of the files in the '
..\Divine Divinity\Run\Dynamic' folder.
This folder is used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied from that folder when you save a game. The files will be re-created as required the next time you start Divinity. If there was a corrupt file in that folder, deleting the files should fix the problem.
