So, long story short, I have 3 instances (from what I have noticed at least) that gold went missing.
First one was on my main char when I switched from wt2 to wt3, and lost about 500k.
The second one was when I logged in on my new lvl 1 wt2 character, at the time before creating it I had 17m gold. Once I logged in on the new char my gold was the same, however when I switched over to my main char, the gold got reduced to 14m.
Third one was from just relogging into the game, same char but the gold got reduced from about 23m to 18m.
Is this a world tier switching bug? And before you ask, no i didnt use it on anything, it just went poof .
