I'm noticing some odd behaviour in Guild Upgrades. Pinging this endpoint repeatedly, I get two different-sized payloads each time. Might be some sort of sharding issue?
EDIT: It's not just the upgrades listing. I'm noticing similar issues in the treasury: I'm noticing the list of 'needed_by' upgrades for items in the treasury alternately growing and shrinking, sometimes dropping upgrades we know we have unlocked. There's definitely something weird going on with at least a segment of the API.
