Accidental Quest Reward Screen Close

I just finished a quest, the reward gem selection screen popped up and by accident I clicked the ground (hence my char moved) and the screen closed.

Now I am without a quest reward because I'm stupid.

Suggested fix: Make it impossible to close the window until the reward has been selected.

Just talk to the person again and one of the dialogue options will be "Claim quest reward" or something along those lines. Click it and you'll be able to choose your reward again.

I have done this intentionally when I was displeased with the quest rewards. I was hoping that they would change if I came back later. They did not.
