Thanks again..
Here are the 4 files in zip.

Nothing amiss there. Let's try another approach.

First, remove (i.e. delete) all the OPC debug-logs. Then add item(s) to the cart, start OPC and click on one of the Shipping options to expose the issue.

Then, zip-up (it gets big) the OPC debug-log and either post it back here or send it to me via PM.
