Gold not displayed or received after daily win and quests
I finished playing games yesterday and distinctly remember being at 49.800 gold because I considered playing a few more games to hit 50K. Logged off regardless, and wanted to hit it today. Had 3 750g quests (kill units and 2 cast red spells, don't remember the other colours for both). I won my third game and excitedly called out to a friend "hey look, finally..." before realizing my gold wasn't at 50K even though I should have received 1750 gold (finished two quests and it was my first win of the day). The reward for XP and gold did display and I did receive my XP, because that turned me level 90, and I have also properly received the mythic card reward for hitting that level.
I tried restarting the client because that sometimes solves the issue, but after restarting I was still at 49.800.
I then played games until I had another win to see if the issue could still be reproduced (which I did think was rather risky for in case it didn't update once more, effectively wasting even more gold). I did not finish my quest, but I did get my second win and thus 100 gold. It properly updated to 49.900 this time.
Can someone see what happened to the previous amount of gold? Especially since it was two max-level quests it hurts quite a lot that these seemingly weren't added.
Thank you kindly for your help in advance.
