Version 3.24:
Some users reported crashes at logout when using the Reminders plugin. This might have to do with either (1) calling Turbine.PluginData.Save() within the plugin.Unload() function, or (2) assigning a callback function in Turbine.PluginData.Save(). (The latter might cause a crash if the callback is called after the plugin apartment is unloaded.)
Adding the same workaround to SequenceBars, because I can't see why the problem would manifest in one plugin but not the other.
