Do you know if this only started happening recently, and if so, can you give an estimate when you started to notice it?

I think this is fixed? I know I noticed it awhile ago.. but everything seems to be showing the correct progress when I click on the link now.

This should be fixed now; can you confirm?

So, a bunch of those battle achievements were fixed, but we missed Mad Miscalculation! It's now been fixed as well as the others. Hopefully that's all of them?

The fixes are not retroactive, which means it won't retroactively reward the achievement to people who should have gotten them - You will unfortunately still need tickets for that. But the achievements will get triggered correctly from the time of the fix moving forward. (Which, for the other achievements, was a couple months back - don't remember the specific date. Mad Miscalculation I fixed a couple days ago thanks to your report <3 )

I am still looking into the incorrect progress (the original bug report) and will keep you guys updated. I know it has been broken for a long time and that it's been frustrating - I think the reason is simply because it's been a lower priority issue compared to other issues we've had- since it is an issue with the display only (your actual count is still there and still correct, just not showing up correctly when you use a specific kind of link) - and it also happens to not be a quick-and-easy fix unfortunately. So we haven't had the resources to tackle it with a solid effort until now. Anyway, I will keep you guys updated on this. :)

This should now be fixed for real!

Whoops D:

Just deployed another fix, so it should be all good in like 5 minutes

Thanks for pointing that out! Just deployed a patch for that, hopefully the last problem we'll run into tonight?
