Dodgy behaviour on ipredict

Tonight I have tried to execute a couple of trades but it seems that orders that exist in the books disappear as soon as you try to trade based on these orders. I have had it happen for both B.E.OHARIU and NZ.RECESSION. Any idea what is happening?

If the person who created the order no longer has the funds to execute the order, then it won't go through. I recommend executing the order anyway with the minimum number of stocks, just so that it disappears from the order book.

Aha! Thanks.
