@Sonikku: Zip has been updated with a fix for this.
@deathemperor: try the following:
In functions_ucs_shared.php find
PHP Code:
$points = round($points, $vbulletin->options['ucash_rounddecimal']);
$points = number_format($points, $vbulletin->options['ucash_rounddecimal'], '.', $showcomma);
Replace with
PHP Code:
$points = vb_number_format($points, $vbulletin->options['ucash_rounddecimal']);
If this works, when I get around to rewriting the hack, Im scrapping the ucs_number_format
