These fixes are live on the server as of last night's restart.
Server freezes (Aug 2)
The server locked up twice on Aug 2: once around midday and again in the evening. During a freeze, logins stalled before the character screen and everything in the world (gathering, feeding, movement) stopped responding until a restart.
Root cause found and fixed: a rare timing collision between a buff expiring and a player update being sent at the same instant could deadlock the server. The odds went up with more players online, which is why busy hours were hit. The collision has been removed at the source, so this class of freeze cannot happen anymore.
Livestock feed and supplements
Combined Feed and Livestock Supplement could show "Not enough items." when trying to care for animals, even with hundreds in your bag. Cause was bad stored data on the item stacks themselves (they showed a red name and a grade feed should never have). The broken stacks have been repaired.
If your feed still shows a red name, relog once and it will sort itself out. If it refuses after that, file a bug report and we will fix your stacks directly.
