Thank you for bringing this to me. Please answer these questions as it'll allow me to debug:

Which version of factions are you using? Are you running EpicSpawners? (if so, what version)

Someone is probably calling an event asynchronously and causing that CME. I've added a patch which should hopefully resolve that issue, please test and let me know how it goes. https://drive.google.com/open?id=0B8XNBcgBSdHyWFRITE90QU9WZEE

Factions 2.10 and not using epicspawners. I will test!
