While hoeing my herb patch, I received a modestly sized ruby as a bonus item... and then a second one. Prior, I was experiencing quite a bit of lag between a command (harvest, hoe, sow, water) and the action. Might be related?
Oh, running firefox 12.0 and a slightly older version of flash, but I never encounter issues normally and this doesn't strike me as the type of thing to be affected by that.
edit: this is deliberate according to the change log. fuel cells as well. handy!
