i was playing arena the other day and was skipping through the reward sequence as quick as possible like usual. i thought i noticed getting a gold reward, but also noticed i still only had 5 gold. i didn't think too much of it as i skipped through rewards.
today i started arena and had 120 gold left over. i did amazingly horrid with a 0/3 run. the rewards showed that i received a card pack and 30 gold. never got the 30 gold.

i "think" this is twice now i haven't received my gold reward. but for a fact it did at least happen this last time.

anyone else having this issue?

You get the gold before you open your rewards, as soon as your arena run ends you have already received the rewards which is kinda stupid but that's how it works

yes, but i went into the arena with 120 gold

You sure it wasn't dust? Usually you get dust for horrid arena runs, at least in my experience.

i was pretty positive at the time. maybe i was mistaken though. 1 thing i should mention is that it's not every arena run. i've been paying attention since the first time i thought it happened. it is actually very likely i went 0/3 in the first run i'm not positive about. i did 0/3 a few days ago mistakenly trying to knock out some quests.
i'll keep screenshots from now on and post if it happens again.

nothing to post about.. you were definitely mistaken sir
