Bug in tactics scoring

I am posting this on behalf of David-09.

There seems to be a bug in the scoring of the tactics training. A few days ago, after a single wrong answer, my score dropped by 9 points. However, the wrong answer was scored 9 times in a row (the last 2 times with -8 points each), resulting in -79 instead of -9 points. When solving the question, my internet connection was not always stable, so this had an effect.

If this is a bug, can my training score please be readjusted?

Training rating can't be changed other than by solving puzzles. No good reason for it, either. Also, the question is rather incomprehensible. Are you saying you got -79 rating from solving a puzzle incorrectly 9 times? Your training rating shows a drop of 15 points from 1 puzzle on March 18th, so it was probably buggy due to your lag and didn't actually count.

It's not about my training rating, but David-09's.

He solved the puzzle incorrectly once, but he got -9 (7 times) followed by -8 (2 times), all on the same single puzzle (same puzzle number).

He can still see this as well as the total of -79 in his history of previously solved puzzles.
