Yes I saw your message about the score updated once but there are the 2 modes, the feedback mode ( which is mentioned on your answer) and the "When completed a quiz " mode where it is indicated, in the description, that the points would be given only the first time if we allow members to play several times so I thought the points would be updated in the first play on a quiz.
I thought the description was correct but it was missing the function
No worries for the source code, I will not mention it on the forum.
For the Beta, I understand it, that's why I went back the bugs that I met. If I encounter a bug, I guess others will have it too or will ask the same questions so I wanted to help.
