Portions of gold disappeared from all my chars after a 1 year hiatus

So I just returned after being away for a year, and I noticed EVERY character had way less gold then before I left. I use Accountant (and a gold datatext from ElvUI) and they showed me a total loss of over 200k, and I can't for the life of me understand where it went. I've only been using my own computer to play WoW, and the addons where used before my hiatus.

Anyone that can offer an explanation of what could've happened?
