WIRE FIX. DLU sent NotifyNotEnoughInvSpace with the ID of
VehicleNotifyFinishedRace (1396). The 1.10.64 client registers it as
NOTIFY_NOT_ENOUGH_INV_SPACE (1516, 0x00545c90) and reads freeSlotsNeeded
followed by the optional inventoryType (0x00d8b850), which is what the
payload already was. Only the message ID changes.
