Just had the same crash twice in a row on PS4. That wouldn’t be such a thing per se, but let me explain a little further.
I was doing 2 tasks, a daily (7 arena wins in a row without losing) and a 2nd (8 arena wins in a row without losing). I had won 6 without a single loss when the 2 crashes occurred. Even though I technically won the match, it counted as lost. After the 2 losses, of course, I was being brought to the rewards screen. Rewards for 6 wins. OK, but the 2 tasks were set back to 0.
Now, I’d really appreciate some form of compensation for the time and effort I invested in vain. I’d be OK with just the compensation for the 2 tasks being completed (3000 gold for the 7 win, 10 gems for the 8 win). And, if possible, to remove at least the 8 win arena match from my list of tasks as, to be honest, I am not going to play the arena again until this problem has been fixed. The daily task will change soon enough anyway.
If you need more details, please let me know.
Looking forward to your reply and thanks in advance.
