There are two significant changes to the Vantage driver since v4.8.0. 1. Commit b0145b3 <https://github.com/weewx/weewx/commit/b0145b34c2d72562d1ba54c113b29d693ead375e>. See Issue #772 <https://github.com/weewx/weewx/issues/772> and this email thread <https://groups.google.com/g/weewx-user/c/iSuLD9EtIt0/m/bXj3-MblEAAJ>. This tries to make "Expected 99, got 0" errors less traumatic.
However, it would affect genLoopPackets(), not genArchiveRecords(), which is where your error is occurring. 2. Dealing with "ghost values." Recall the discussion last spring about values being archived for sensors the user didn't even own, especially on VantageVue. The fix was to not decode certain values for the Vue. This has nothing to do with pulling values off the station, only what happens to them afterwards. I don't see how the onboard clock time would cause this. It would only affect archiving on the server, not faults in the logger. In short, I'm at a loss as to what could cause this. How often does it happen? Every single archive record? Every once in a while?
