Hi - now and then (luckily not too often), I see a Paypal payment that 
has no associated IC order. I have to email the person who paid and ask 
what they ordered, which is not ideal. I see:

Error during creation of order routing log: Route log failed.
at /usr/local/interchange/lib/Vend/Order.pm line 1856

Any hints on how to diagnose? Thanks!
