Hi,

Okay here are the challenges before I try upgrading an artifact:

Here is a random lvl 1 artifact that I am going to upgrade to lvl 8 (Notice my silver in these first 2 pictures is 231,306)

Here is the artifact after I have upgraded it to lvl 8, notice I have spent silver to do this (silver now at 199,026):

And finally let's return to the challenge screen, here you can see my silver is at 199,026, proving I took screenshots in this order:

I have spent around 400k silver trying to complete this challenge on different combinations of hero rarities and artifacts.

i have the same damn issue!

Im stuck at upgrading 3 out of 6 artifacts and 3/12 artifacts.

I completed the 3/3 yesteday, but now, after the patch, i upgraded LOTS of damn artifacts to level 8, specially for this challenge, and the progress did not update. Lots of silver down the drain! Makes you think 10 times before buying silver for real cash, with this bug in the game. At least its nice to know im not the only one. For me, it also sucks because i was depending on that energy from challenge rewards to uprade my last 4^, so i can get my last 5*, so i can get my first ever char to rank 6.

I would attach a screenshot with the challenges, too, but guess what, the servers are down for like the 7th time today.

Also, i could not claim my clan chest, when i tried to claim it, it said "clan boss chest could not be found, or something like that. And its shitty cause i qualified for the highest reward for that boss! I checked my inventory for new item, and guess what, nothing new was added.

Sorry to say it, but this patch is a total crapfest.
