Game returning currency (possible game breaking)

Hi comunity,

Noticed something VERY concerning today, so very fast contextualization.
Bought everything on the new race vendor and ran out of tickets -1 hour later all got returned and I retained items.
On this vendor I got 4 mayhem books - sold them for like 1k- now I have the books back in my inventory and retained the gold from AH.
Upgraded my gear from 1340 - 1349 (had 8k gold) and wen I ran out of mats had 2k - didn’t sell anything, but wen I reloged I had all the gold spent and retained all upgrades.
and now my guild mates reporting that they are one shooting almost every upgrade in T3 (30% and 15% chance).

Might wanna look into it FAST.
