In Stack Overflow, I reached my daily vote limit on 39. However, I cast 10+ question up-votes before reaching 25 total (Q & A votes), but I didn't get the 40 total.
What did happen is I tried to down-vote on 1 answer, but I have less than 125 rep, so it showed the following dialog:
Thanks for the feedback! Once you earn a total of 125 reputation, your votes will change the publicly displayed post score.
I believe it took 1 vote from the 40 limit.
Edit: (+info after @RobertLongson comment): Even though the down-vote may appear later, it does not show in my activity page, and the "vox populi" badge shows 39/40 (still not earnt).
I've already read the following questions:
- What are the limits on how I can cast, change, and retract votes?
- Separate vote pools for questions and answers
- Daily vote limit hit before reaching actual counts?
- Please don't require answer votes to be cast before question votes
- Cannot vote on question although 40 votes limit not reached
- Did Stack Overflow remove the 10 additional question-only daily votes?
- Daily vote limit reached; vote again just now
- Says I reached my daily vote limit for comment upvotes? and
- Maximum voting bug?.
Still, I think this may be a bug.
Edit 2: This is the list of all 39 up-votes, first one around 2:00 am UTC
