This is not a bug, the question is older than 60 days so the migration option is disabled.
See this Meta Stack Overflow Post:
questions older than 60 days should not be eligible for migration, either by normal user close-votes or by moderators. In extreme cases, we can perhaps provide an alternate means of moving old questions, but under normal ...
There's one requirement missing for you to get the badge; see https://dba.stackexchange.com/badges?tab=tags (emphasis mine):
If enough votes are earned in a tag with 100+ total questions, the badge will be automatically created and awarded.
The innodb tag only has 43 questions at the moment.
It is my understanding that as questions are deleted, or in some other cases, the questions you vote for still show in the one list but are obviously no longer counted in the other.
Good catch, but as far as I am aware, this is "the way it is supposed to work". I'll get confirmation if I can in the form of a Meta meta link.
Different Value of Votes in ...
A given question tag will specify markup to be used throughout the question (there are rules, but effectively the first "language specified tag" will set the tone for the entire page), but to override that for a specific answer, or portion of a question (as you're demonstrating in the linked bits) you would need to refer to the aforementioned question:
When I open the SO link while not logged in, I end up at the "wrong" question, the one you linked first, i.e. ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
However, when I am logged in and click the SO link, I am redirected to this DBA.SE question: what is the solution of these errors?
The latter is closed as a duplicate of ...
This isn't a bug, it's status-bydesign. The unupvote is the confusing piece.
Your rep for Nov 17th shows a -10, but this is actually impacting your rep on the day for the original vote, July 30th. When an unupvote happens, it's like the original vote never happened...poof, it disappeared on July 30 along with the rep, even though the action happened much ...
Was this an oversight ?
No, this was intentional.
We ran some analytics and found that very, very few people made use of those share buttons. And while I'm glad you found them useful, considerably more people actively resented them.
Since they weren't really working, weren't really popular, and were cluttering up every question we removed them.
May we ...
Was this an oversight ?
I think this is just an "improvement" that's still in the experimentation stage.
Is Twitter being removed ?
Well, possibly. The metrics don't support it being used on a regular enough basis to be helpful, as I understand it.
Is there another form of Question/Answer promotion being done or in the works ?
Yes, they are tweaking ...
When you're looking at your network accounts on a site, e.g. SO from DBA, this is pulling from a network-level cache that can sometimes get out-of-sync.
We periodically fix this cache for all users (which is very expensive), but this is usually not needed. The implementation is such that upon getting another badge or more reputation, the network cache ...
