I recall that it was 1m big blinds, 500k small blinds and a 25m minimum table.
I had joined with 25m, slowly worked my way up to about 69m.
The hand was four spades, I bet 1m on the flop and 1m on the round after. That would have put me around 67m maybe. The river gave a fourth spade and my opponent, kimberlee  bet 10m. I hit the fold button, but nothing happened, and then I timed out.
I rejoined the table with 25m, not noticing I had lost all the 65m from before, and it took me about 5-10 minutes before I looked at my money on hand and noticed it didn't seem very right.
I posted the bug, then on the same table, asked kimberlee  if she had maybe put me all in and I clicked call or something on accident. She confirmed that was not the case, and I had just timed out.
So the money just disappeared.
I noticed that another player filed a similar report around the same period of time that this happened to me, so I am going to guess that this happened within the same time period.
I think I found that game (gameID 219518), but I don't see any time outs. Regarding to logs: You set down with 25mil at 2011-09-29 05:36:13 and keft the table with 24mil at 2011-09-29 05:44:11. Perhaps I missed something?
Well, as you can see from my original post, I had already been playing as of:

That would likely place the time of this happening around 5:25 I would guess.
I did indeed go back and sit back down at the same table with 25m, played one hand asking kimberlee if I had gone all in before, and after she confirmed I had not, I left the table. This would have corresponded with what you have listed:
2011-09-29 05:36:13 (as returning to the table after posting the bug)
So the incident would have occured on the same table, but during the first time I sat down at it.
Woulda been sat down with 25m and then timed out at some point.
*Edit* - And I also am pretty certain that I would have sat down a total of 3 times at the table. The first time is when the bug happened. Then I sat back down with 25m, not realizing the money was gone. Realized the money was gone, got off the table, posted the bug. After posting, got back on the same table, asked if I had made a mistake, confirmed I had not, and then got back off the table.
Checked the logs tarting from 2011-09-29 05:20:04, but still don't see any time outs there It also bad that you set down again and played after this happened, we now can't be sure, what exactly caused the problem. I will write Clansy or Hydr0, there is nothing else that I can do here.
