Libhistoire linked events missing

[Archboobie]

When I logged into the game this morning, all my stored events in Guild History are missing, but the linking shows all green/blue, and my ATT page is showing incomplete data. I have not added any new addons or done anything since I played yesterday. I tried to manually get it working by spamming "E" but it will take me a lifetime to link all my historic data...

If you look at the ATT screenshot, yesterday my sales in Dark Shadow were over 400k, today it's showing only 190k so clearly missing the data. There isn't even any data for last week for my guilds. I have no idea what happened or what I have done but I'm missing more than a year's worth of data lol

All my addons are up to date and I use Minion to manage them.

Can I find this data somewhere on my pc and re-upload it?
