Following up with a request to post here. I have the same experience as EF321. If I immediately go to my guild histories upon logging in, I can load them just fine, but if I wait at all (even as little as 30 seconds), it gets "stuck". If I stay logged in and just wait it out, it can take an hour or two to finally finish, and my cache
for specific guilds has a high chance of corrupting and needing a reset to load any data. I went ahead and uploaded my LibDebugLogger.lua:
