I am affected by 2 bugs, and this is the second one that leads to me not receiving my gold of 300, even though I had an active run during the affected period.
The first bug is the one that causes my battleground rating to drop by 300+ in a game, which the GMs have said they cannot do anything about it than to ask me to post in forum.
For the bug with 300 gold, again, submitting tickets to Blizzard support only leads to me being redirected to “try asking in forum and see if the developers bother to reply”.
