You don't need to restart the bot after editing Spawns.txt since its only used when starting the bot, not when it is already running. Just PM !unload all to the bot to unload all existing plugins (notice you can !unload # to unload a single plugin, the number you need can be found from !plugins). You can !load to load a plugin. You don't need to include the .dll part. As SOS already said the message must be caused by a plugin. Make sure you have !unload all and check if its still appearing. Maybe making the bot sysop might help some too, dunno if you already did this.
