Custom Vending Machines Broken?

[yetzt]

Custom npc vending machines appear to be broken. Placed vending machines are empty and when using the rustedit.vending.restockall command, this happens:

Error: rustedit.vending.restockall - Object reference not set to an instance of an object (Assembly-CSharp)

and logfile says:

ent.killin the vending machines shuts up the log.
