array_merge(): Argument #2 is not an array

Hi everyone,
I am trying to fix up an old mod that is now unsupported by the developer.
I am not a coder and am struggling to understand how to fix a server error it is giving me.
I have managed to fix other errors through googling and trial and error, but this one is defeating me.
I don't think it is anything too complicated, but needs someone who knows what they're talking about :D

Error Info
ErrorException: array_merge(): Argument #2 is not an array - library/XenAuction/CronEntry/Auction.php:92
Generated By: User1, A moment ago

Stack Trace
#0 [internal function]: XenForo_Application::handlePhpError(2, 'array_merge(): ...', '/home/mysite...', 92, Array)

#6 {main}

Request State
array(3) {
["url"] => string(61) "http://mysite.com/index.php?auction-process/expire&id=6"
["_GET"] => array(2) {
["auction-process/expire"] => string(0) ""
["id"] => string(1) "6"
["_POST"] => array(0) {

Lines 91 + 92 in auction.php are as follows....
// Set phrase params
         $args        = array_merge($auction, $bid);
I have attached auctions.php for anyone who wants to look at the full file.

Thanks to anyone who takes a look.

It's bad form, but you can try forcing php to cast the variable as an array by tacking (array) to the front of it. For example:

$args = array_merge($auction, (array)$bid);

You might get an error about something else later on, but it also might be just hacky enough to run...
