[2020] Please help, 1200 gems have dissapeared

I bought a salvage of gear from the guild store for 840 guild tokens. After checking my character to see if I needed more salvage, I realized 1200 had disappeared from my balance. I checked all the store pages to see if I had bought something (it would have been grayed out), but I had bought nothing with the gems. Please help. What the hell has happened to my gems. I spent a very long time collecting them, and now they are all gone. Has anyone experience something like this before?
