@AlexV might be that you reviewed everything in the queue, but the items in the queue have not been cleared yet.
soo ... blame caching, I guess ..
 
I'm experiencing the same thing aws with "suggested edits" and "close votes"
 
7:52 PM
soo ... there's 11 items in the close queue, 5 in the suggested edit queue, 3 first posts and 2 reopen items
usually I don't touch the queues, because I can't vote :/
 
All the below-3k-queues show 0 for me.
 
@AlexV that is ... confusing..
 
@Vogel612 I can confirm the close and reopen votes. They are there.

IIRC we were one of the sites that was more vocal about the review indicator changes back then
poke @dfhwze I kicked this question out of the close queue
Just because a text adventure doesn't need more than a paragraph of explanation for the code that doesn't mean it lacks context
 
My comment is removed, what did I say? :)
 
8:13 PM
sth like "sounds interesting, but off-topic. lacks context" IIRC
 
even less than the actual close reason and a request to edit the title which was obsolete
note that the close reason "Lacks Concrete Context" is specificially about the way the code is written and not the "non-code" explanation we expect from questions
 
@Vogel612 To be fair: I started to edit the question title before his comment was posted, but finished it after the comment was posted.
 
Yes the Title was edited by Alex after my comment. The title bothered me the most.
 
It's clear how the code is used, it's not hypothetical, stub or obfuscated code nor asking about generic best practices
the LCC close-reason doesn't really apply
 
8:16 PM
@AlexV nothing terribly wrong with the comment aside from it being obsolete
 
see the recent comment .. =D
 
@dfhwze that is a significantly better comment. Note that it is also actionable
It clearly tells the user what they can do to improve the question :)
 
You are tough on me :) I did state in my comment to change the title ...
 
"Also provide a better title" doesn't help the user...
It just tells them you consider their title bad. It doesn't outline what's a good title :)

btw, I tried to put Mast onto that quite a while ago. Even if the post is really great it might just share the fate of Kaz's feature request :D
