I never realized that schedulers are not bound to a plugin, if the plugin author does not add the plugin parameter to the scheduler. But no one, except mob plugin does that. This caused PluginManager to cancel schedulers even if you reload another plugin.
With this update, PluginManager scanns every ten seconds for schedulers and if they dont have a plugin attatched to it, PluginManager detects the plugin and attaches it then.
Schedulers are now forced to be tight to a plugin. Reloading a single plugin wont break other plugins schedulers anymore!
