So just a little while ago i was flipping out because i was 2 rep away from my 10k rep goal
but then all of a sudden it was then 10,008 rep because someone upvoted me. however i didn't get any notification about this +10
now as you can see in the screenshots above, over the past 2 days i got 2 upvotes to a question i posted, however the notifications only shows 1 +10 notification. and they system knows i got the upvote because i knew that i now have access to mod tools.
I am on a Windows 10 Laptop using Chrome 78.0.3904.97 (Official Build) (64-bit)
