The Auto Bumps have a bug, which is that when you disable it on Config, which apperas in the threads list, in the main forum of the game, then in the thread if you edit the thread the option still appears checked "[V]". If you press in "Save", after do some change, like change the price, anyway it not activates the Auto Bump, but can generate confusion as then is not possible know whichs threads have the Auto Bump as if you disable it with Config then still are marked. Also the only way to disable it is with the Config, as if you disable in the thread it not works.
