It's a possibility. I did flit between servers for a bit, but I don't recall if I ever played Arileth on EE, I know I did in the original.
Edit: I couldn't find anything in my steam folder from Arileth, I'm also not subscribed in the workshop. However! I logged in today, and found that most of the gold was refunded, and the item is now valued between 4900 and 5200, so I'm happy. I dunno if a script caught it, or one of our intrepid DMs/Devs was able to check my character's inventory and gold history and simply made the correction manually. In any case, I'm super pumped and super thankful!
