Way to commerce_checkout_complete($order) and still have users return to commerce's payment completed page.

That is at least an option to work around the root of the problem not having access on the page commerce provides after check out. The problem with this solution is we are still routing the use off that page and it is never used hence other hooks that are used on that page are useless. ie. any module implementing hook_commerce_checkout_router would now break.

Thanks for the possible solution not to hack my module but I am still stuck with the problem of not hitting that page...

Here is commerce_checkout_router() it make a call to commerce_checkout_access().. that is returning FALSE and causing the return page not to display since I am calling commerce_checkout_complete($order) because

// Return FALSE if the order does have a uid.
if ($order->uid) { return FALSE; }

my order does... :/

I am still awaiting feed back from the commerce guys...
