Disabeling a Product does not work

[SamueL370]

Hey, at first I would like to say thank you for developing this extension, because for me it is necessary to maintain my webshop, or at least it makes maintainance a lot easier.

And here is my problem:

After installation everything worked fine: I can enable the stock option and see the current quantity. But as soon as I try to enable the "disable products automatically" function (or wthatever it is called) in the producttype menu, contao shows me an error message after I have ordered (after clicking the order button) the last available product in the webshop (if there are still one or two products in advantage it works fine). That is the error message:

Fatal error: Uncaught exception LogicException with message The model instance has been detached and cannot be saved thrown in system\modules\core\library\Contao\Model.php on line 434

#16 index.php(20): Contao\FrontendIndex->run()

Is there a solution for this problem? Thank you very much for your help!
