Describe your problem, including steps to reproduce it

Placing an item in the item routers buffer, then add send mk2 or mk3.

Any other comments?

I encountered this problem after putting a pull mod that filled the buffer then adding the send mk3 so i can configure it before getting a destination.

Stack trace, please.

I don't understand why you would need this, the bug easy to replicate.

OK, same problem as #60 - there will be an update out in the next day or two to fix that.
