This question already has an answer here:
There are some badges which track your presence on the particular stack - enthusiast and fanatic are the two that come to mind that appear to be available on all stacks with consistent criteria (30 consecutive days visit, and 100 consecutive days visit, respectively). However, it seems that tracking your "appearances" on these badges is inconsistent - for example, in spite of visiting all of my (other) stacks on Saturday, some of my stacks - Retrocomputing, for example - did not increment, and when I did not visit at all on Sunday, some of my stacks - StackOverflow, for example - did not reset to zero.
How does the SE network track this, and how can I ensure that a visit to a particular stack is recognized - or that a failure to visit is recognized?
Note: the Consecutive-Days-Problem-#97 is accepted as an explanation for the resets from Saturday - but it doesn't explain why they didn't all reset on Sunday, when I didn't visit the SE Network at all.
