Stuck in auction by selling crystite

[Robbie]

In game http://www.planetmule.com/hi-score-game/game?game_id=11557
at Round 5 i (Host) sold crystite to Player "abloker".
After selling 3 items the selling was stuck, time bar too.
I moved away from the selling line and then time bar moved on.
Went back down to the line then time bar stopped again. But sellling didnt work.
I left the line and let the time of the auction end to make the game go on.

Then, in Round 6 Player ablocker lost his connection and i had to kick him.

I guess the reason that the game act this way is high ping rate to the host for one or more players.
