It appears the issue is caused by ibproarcades code.

I was able to fix this problem by editting the arcade.php and changing this

					$vbversion = substr($vboptions[templateversion],0,3);
					if ($vbversion != "3.0")
					{
						($hook = vBulletinHook::fetch_hook('ibproarcade_new_champ')) ? eval($hook) : false;
					}

To this

//					$vbversion = substr($vboptions[templateversion],0,3);
//					if ($vbversion != "3.0")
//					{
						($hook = vBulletinHook::fetch_hook('ibproarcade_new_champ')) ? eval($hook) : false;
//					}

The code was disabling the hook.
