Disappearing Creeps & Remaining Lives

Hello,
I'd like to report a bug I experienced around 1AM GMT+1 on 3.1.2013.
The problem was, that sometimes, even when a creep got thru and was supposed to take a life from the player and go again in the maze, it didn't take any life and it disappeared, not going in the maze again.
This happened on RW and later on other maps too, most notably on SV, where you can really notice that, if you save for a ray and it goes thru but doesnt take any life or go again in maze.
Any ideas what this could be causing? The games around that time also were a bit laggy. This bug was experienced by all the players in the game, it was not a local problem on my device, everybody in the game saw what was happening and we discussed it in the chat.
I attach my replay of the RW because i dont have the replay for the SV game, which would be better because its shorter.
Here are some examples of the bug in the replay:
7lvl nova goes thru and nothing happens - lilie
20 lvl nova goes thru and nothing happens - 110
AND MOST NOTABLY: 27 lvl 2 demeter go thru and nothing happens - 110
