mysqli->query(); works sometimes - php

Question

i have a kind of problems here and i don't know how to solve it... google said nothing and the search function here didn't shown me anything...
i use this code
$GAME_DB = new mysqli($__CONFIG['MySQL']['HOST'], $__CONFIG['MySQL']['USER'], $__CONFIG['MySQL']['PASS'], $__CONFIG['MySQL']['DB']['GAME']);
if($GAME_DB->connect_errno) { echo $GAME_DB->connect_error; exit; }
$VILLAGE_DATA['villageID'] = $mysqli->real_escape_string($VILLAGE_DATA['villageID']);
$query = "SELECT name, level, time FROM actions WHERE type='build' AND villageID='".$VILLAGE_DATA['villageID']."'";
if($result = $GAME_DB->query($query))
{
// table header
while($row = $result->fetch_row())
{
// some rows in here
}
// table footer
}
there aren't any syntax errors in that query and the results are there!
sometimes the query is successful and i see my table but sometimes (for example: when i reload) i receive the error message Commands out of sync; you can't run this command now
how can this just work "sometimes"? where is my problem?

http://dev.mysql.com/doc/refman/5.6/en/commands-out-of-sync.html
If you get Commands out of sync; you can't run this command now in
your client code, you are calling client functions in the wrong order.
This can happen, for example, if you are using mysql_use_result() and
try to execute a new query before you have called mysql_free_result().
It can also happen if you try to execute two queries that return data
without calling mysql_use_result() or mysql_store_result() in between.
But from the code you've posted I don't see how this could happen. Either there's more code than what you've posted and something there is happening out of order, or your MySQL connections are being improperly established/pooled/persisted somewhere outside of PHP.
