Here is one more big problem:
If csdm amxx module is inside modules folder, it can not be prevented from loading even if all plugins for recsdm in plugins.ini (or any other .ini file) are stopped.
Even if you put semi-colon (;) before csdm inside modules.ini, it does not stop.
It causes big problem if server has two modes (Day PUB night DM).
edit: Seems it is not only problem for csdm. It's problem for all modules (even if there is no activator for amxx module, it's enabled by default with latest amxx).
