Frustrating time tracking down error fieldnames.

For the past week or so I have had field not found issues when opening a particular table.  Spent hours trying to find the missing fields as reported.  Even Ninext could not see them.  I kind of thought hmmmm maybe a Ninox issue?  Well this morning the table opens just fine.   I check the version and I see we have moved to 3.11.6.  I wonder ;-)
