Very confused on this one, the faulting line is reported as inventoryTypes.RemoveWhere(type => !module.InventoryTypes.Contains(type)); But I don't see how anything there can be null, without there also being an ArgumentOutOfRangeException

Log was empty otherwise, can't tell you anymore sadly I will keep checking the log between restarts if it happens again
