Got this error since installing new Loot Manger Plugin

 

Exception while calling NextTick callback (NullReferenceException: Object reference not set to an instance of an object)

Put o.reload PogoStick to server console and send a screenshot to me.

Send your PogoStick plugin config 

with o.Reload nothing will happen, but if I to a o.reload BetterNpc, I will get this message
