@tuckley I just had the same thing happen. I lost on time even though I moved and my opponent's time clicked down. We even debated in chat on whose turn it was.
Bug Report

In tactics trainer, if a network error occurs and you try to make a move, the site pops up an error message saying "try again", you try again couple of times and if the move is wrong you get your rating reduced as many times as attempts that you have made! This works only in one direction...

I lost om two games because i was disconnected, but my internet connection was fine. I was playing on an ipad 2 via a wifi connection.
Bug: Button in four-player chess says "Claim win" but I clicked it and my opponent won.
If the result of clicking the button isn't to claim a win, then it should not say "claim win". The label on the button should indicate what it will do.

Not sure if anyone else has experienced this, but I just played computer-Hard and it just stopped moving after 2 moves. Then after about a minute, it declared that I had lost due to game abandonment.

How should we know? This is not chesskid.com. I have never used chesskid.com.
I went over today and it looks like you are asking for help to solve the after lesson questions. It won't let me attempt the question until I have solved all 31 previous levels.
Sorry but I really don't feel like doing all of them, just so I can take a look at the puzzle.
Maybe if you post a screenshot of the problem you are talking about, we can help you out.

BUG:
In chess960 correspondence, the moves are recorded incorrectly, It thinks my queen is a knight one move, and a bishop the next! But the main point is that moves are recorded at the wrong square, and with the wrong piece! It is in my Team NZ against anatta, I don't know if it bugs in other games
I have reported the same problem twice today without any feedback and the problem still exists. The problem occurs when I win a game against any player in the 46 th chess.com tournament under 1000 a specific player Roisehaken scores one score plus one tie break instead of one tie break only. This happened during the last three matches won. Full details is available in the section where I reported the bug problem.

I just lost two games because i played a move and it did not register for my opponent but on my screen, the opponent's clock kept ticking down.
