i did not in this situation, also in the most recent one I got it wrong
Why do you go down in puzzle rating when you get it correct
ok here is a series of moves leading to the end when it gives me points for partial credit but i lose even when it says i gained
Looks like a display issue. You lost points on that puzzle.

here is it happening again, i clearly lose way more than what is says i do

is this going to get fixed anytime soon?
If you mean the first puzzle not counting, yes
As to the other things you are seeing, I did some brief testing and couldn't recreate. I'll try to test more fully later but it's looking like your browser might have an issue, but until I'm at a full system and can do more exhaustive tests, I can't see if there may be a bug.
kings gambit, sicillian, KID, any recommendations on what to study for the future

here is an example
look at the chart it shown my rating going down even though it gave me plus 8
There is a bug with the first puzzle completed in a session where it doesn't actually get counted towards your rating and won't show in your archive. However the puzzle shows on the graph.
So, if you get the first one right you'll see that but when you get the next puzzle right, your actual rating likely won't be as high and the graph will show a drop.
Staff have identified the cause of the bug so it should be fixed in the near future.
This has been fixed.
