I found a couple of places in the Empennage instructions where the hole count was off, but it was pretty obviously - something like calling out 3 holes and pointing to 4. Sorry, I don't have my notes in front of me right now to tell you exactly where I saw it. There's also one place where the labelling of two parts swapped left and right. These are documented in many builder logs, and are also pretty obvious from the diagrams, but if you're not sure, anyone here will be happy to help clarify. Van's support also replies very quickly.
I do suggest checking Van's site periodically for updates to the plans. I was surprised to find that the wing plans I just received still didn't contain an update published almost a year ago. It was a trivial change that involved deleting a step the factory was now doing, but it didn't occur to me the update wouldn't be included. Come to think of it, my empennage kits had the same change, but the revised plans weren't released until i had finished the kit.
It's always nice to have less to do, but the real lesson is it doesn't hurt to ask if something doesn't seem right.
