Error in Saving Answers

Hi!

There is an issue with version 0.8.6.

When a new question is added with an answer (one possible answer), the question is always saved with first choice as the correct answer, no matter which answer (among many you added) you selected as correct.

However, when you open the question in edit mode and corrects the answer, the change is recorded correctly in the database.
