I ran the Predefined Setup Refresh tool. At the bottom of all the chat window entries there were statements that each refreshed predefined game had 1 Warning. However, that was the only place that stated anything about warnings. There are no warnings in any of the chat window entries for each of the predefined games. Ditto for the error log (which essentially just duplicates the chat log text).
There might be an expectation that if there are statements of a warning for each game refreshed, then there should be at least a warning statement within each of those games refresh entries. Perhaps even explaining what the warning was for/about. Link is to a txt file containing the whole chat windows output.
