Need to upload screenshots to report

You can. See the instructions as posted by Blizzard here:

If you suspect a bug, then I suggest posting to the Bug Report forum (where the post linked above is placed).

I read a lot of posts on the bug report forum. Most of them fall in either of these two categories:

  1. A player misunderstanding an interaction, or missing a card that was played when they were shortly distracted. By asking for screenshots or (better) hsreplay.net links, the interaction can be explained so that the player learns and realizes they were confused and not experiencing a bug.
  2. An actual bug. By asking for screenshots or (better) hsreplay.net links, the interaction can be better understood by Blizzard, and they can recreate the same board state on their test servers. That helps them find what causes the bug, and then they can try to fix it.

So as you see, asking for more information, preferably in the form of screenshots or hsreplay links, is not hating, nor trolling - it is just trying to be helpful.

Since you have the screenshots and now know how to attach them, I am looking forward to seeing your report over there.
